Hide Files inside Image Files !!!

Sometimes we are eager to hide some files on the system !!!

So, now i have got a trick to hide files in image files !!!

Here it is :

** You require WinRAR installed on your PC for this trick.
** First add your files to .rar and i.e. say files.rar
** Say you have a image as img.jpg
** Now, save files.rar and img.jpg in c:\ drive.
** Click start >> Run
** Type cmd
** Now in command prompt type cd..
** Again type cd..
** Type copy /b img.jpg + files.rar new.jpg

-------------- Please Note --------------

>> This command will concatenate the two files into the new file new.jpg
>> Don't type files.rar + img.jpg instead of img.jpg + files.rar.
>> Now, (size of new.jpg) = (size of img.jpg) + (size of files.rar) .

-------------------------------------------

*** Mission Accomplished !!! ***

Now, we have new.jpg consisting of both img.jpg and files.rar .

Accessing the files :

** Double click new.jpg and img.jpg can be viewed.

** Now, to access files.rar :

BandWidth Explained

This is well written explanation about bandwidth, very useful info.

BandWidth Explained

Most hosting companies offer a variety of bandwidth options in their plans. So exactly what is bandwidth as it relates to web hosting? Put simply, bandwidth is the amount of traffic that is allowed to occur between your web site and the rest of the internet. The amount of bandwidth a hosting company can provide is determined by their network connections, both internal to their data center and external to the public internet.


Network Connectivity

The internet, in the most simplest of terms, is a group of millions of computers connected by networks. These connections within the internet can be large or small depending upon the cabling and equipment that is used at a particular internet location. It is the size of each network connection that determines how much bandwidth is available. For example, if you use a DSL connection to connect to the internet, you have 1.54 Mega bits (Mb) of bandwidth. Bandwidth therefore is measured in bits (a single 0 or 1). Bits are grouped in bytes which form words, text, and other information that is transferred between your computer and the internet.

If you have a DSL connection to the internet, you have dedicated bandwidth between your computer and your internet provider. But your internet provider may have thousands of DSL connections to their location. All of these connection aggregate at your internet provider who then has their own dedicated connection to the internet (or multiple connections) which is much larger than your single connection. They must have enough bandwidth to serve your computing needs as well as all of their other customers. So while you have a 1.54Mb connection to your internet provider, your internet provider may have a 255Mb connection to the internet so it can accommodate your needs and up to 166 other users (255/1.54).


Traffic

A very simple analogy to use to understand bandwidth and traffic is to think of highways and cars. Bandwidth is the number of lanes on the highway and traffic is the number of cars on the highway. If you are the only car on a highway, you can travel very quickly. If you are stuck in the middle of rush hour, you may travel very slowly since all of the lanes are being used up.

Traffic is simply the number of bits that are transferred on network connections. It is easiest to understand traffic using examples. One Gigabyte is 2 to the 30th power (1,073,741,824) bytes. One gigabyte is equal to 1,024 megabytes. To put this in perspective, it takes one byte to store one character. Imagine 100 file cabinets in a building, each of these cabinets holds 1000 folders. Each folder has 100 papers. Each paper contains 100 characters - A GB is all the characters in the building. An MP3 song is about 4MB, the same song in wav format is about 40MB, a full length movie can be 800MB to 1000MB (1000MB = 1GB).

If you were to transfer this MP3 song from a web site to your computer, you would create 4MB of traffic between the web site you are downloading from and your computer. Depending upon the network connection between the web site and the internet, the transfer may occur very quickly, or it could take time if other people are also downloading files at the same time. If, for example, the web site you download from has a 10MB connection to the internet, and you are the only person accessing that web site to download your MP3, your 4MB file will be the only traffic on that web site. However, if three people are all downloading that same MP at the same time, 12MB (3 x 4MB) of traffic has been created. Because in this example, the host only has 10MB of bandwidth, someone will have to wait. The network equipment at the hosting company will cycle through each person downloading the file and transfer a small portion at a time so each person's file transfer can take place, but the transfer for everyone downloading the file will be slower. If 100 people all came to the site and downloaded the MP3 at the same time, the transfers would be extremely slow. If the host wanted to decrease the time it took to download files simultaneously, it could increase the bandwidth of their internet connection (at a cost due to upgrading equipment).

Find how Long is your system running?

How Long Has Your System Been Running?

Here's how you verify system uptime:

Click Start | Run and type cmd to open a command prompt.
At the prompt, type systeminfo

Scroll down the list of information to the line that says System Up Time.

This will tell you in days, hours, minutes and seconds how long the system has been up.

Note that this command only works in XP Pro, not in XP Home. You can, however, type net statistics workstation at the prompt in Home. The first line will tell you the day and time that the system came online.

Burn Files Quicker in XP

Convert Fat to NTFS

How To Convert File System, fat - fat32 to ntfs

open a dos prompt and give the command

convert d: /fs:ntfs

this command would convert your d: drive to ntfs.

if the system cannot lock the drive, you will be prompted to convert it during next reboot.

Normally you should select yes.

Conversion from fat/fat32 to ntfs is non-destructive, your data on the drive will NOT be lost.

Be aware that converting to ntfs will make that partition of your
drive unreadable under dos unless you have ntfs utilites to do so.

Find Serial Keys using Google

ok, this is a little trick that i usually use to find cd keys with google.


if your looking for a serial number for nero (for example) goto google.com and type nero 94FBR and it'll bring it up

this works great in google

HOW DOES THIS WORK?

Quite simple really. 94FBR is part of a Office 2000 Pro cd key that is widely distributed as it bypasses the activation requirements of Office 2K Pro. By searching for the product name and 94fbr, you guarantee two things.

1)The pages that are returned are pages dealing specifically with the product you're wantinga serial for.

2)Because 94FBR is part of a serial number, and only part of a serial number, you guarantee that any page being returned is a serial number list page.

Speed up Acrobat Reader

Here's how to do it:

1. Go to C:\Program Files\Adobe\Acrobat 6.0\Reader (replace the C if you installed on another drive, like I did).

2. Create a new folder called plug_ins_disabled.

3. Move all files from the plug_ins folder to the plug_ins_disabled folder except EWH32.api, printme.api, and search.api. There should only be these 3 files in the plug_ins folder.

4. You're done.

Missing Administrator Account - Here is the solution

Once you have created regular user accounts, the default Administrator account vanishes from the Welcome screen, which you see when the computer starts up. Press Ctrl-Alt-Delete twice at the Welcome screen to retrieve the standard logon dialog. You can log on as Administrator from here. To switch among accounts, just click the Log Off button on the Start menu. You'll then see the Log Off Windows dialog box. Click the Switch User button, and you'll be taken to the Welcome screen where you can select and log on to other accounts.

Quick fix for Spyware

OK, so now you realize that you've got some spyware junk on your system.

Before you go headlong into deleting suspected files or editing the registry, try this simple disabling technique.

First, see if you can determine what the offending files are. You can do this by running "msinfo32" if you're using Win98. I only have experience with Win98, so I don't know the corresponding run command for this "Microsoft System Information" utility in WinXP. Go to the "Software Enviroment" section and poke around to see if you can locate an offensive or out-of-place file that looks like it doesn't belong. Make a note of the filename and location.

Then fire up Windows Explorer and navigate to the "no-goodnick" file. Now, and this is important, rename the file to something you can remember later. I like to use the same filename, but tack on the letters (in caps) "OLDXXX", where "XXX" are my initials. So, for example:

twaintec.dll

is renamed to

twaintecOLDXXX.dll

This effectively disables the offensive file, so that whatever piece of spyware junk is looking for it, it can't find it, and thus can't glop up you system. If you've made a mistake and the file is essential to your system, you can easily correct it by reversing the renaming procedure. This is much easier than restoring a deleted file, especially if you have emptied your recycle bin in the meantime!

Some bogus files can't be renamed while Windows is running, so then you have to use brute force and reboot in DOS-only mode, and use DOS commands to locate and rename the file. You may have to dig out your old DOS reference books for this like I did.

I have used this technique several times to disable offending junk until I can find a permanent way of getting rid of it.

It's a great trouble-shooting technique.

Recover a corrupted system file

If an essential Windows file gets whacked by a virus or otherwise corrupted, restore it from the Windows CD. Search the CD for the filename, replacing the last character with an underscore; for example, Notepad.ex_. If it's found, open a command prompt and enter the command EXPAND, followed by the full pathname of the file and of the desired destination: EXPAND D:\SETUP\NOTEPAD.EX_ C:\Windows\NOTEPAD.EXE. If either pathname contains any spaces, surround it with double quotes.

If the file isn't found, search on the unmodified filename. It will probably be inside a CAB file, which Win XP treats as a folder. Simply right-drag and copy the file to the desired location. In other Windows platforms, search for a file matching *.cab that contains the filename. When the search is done, open a command prompt and enter EXTRACT /L followed by the desired location, the full pathname of the CAB file, and the desired filename; for example: EXTRACT /L C:\Windows D:\I386\Driver.cab Notepad.exe. Again, if the destination or CAB file pathname contains spaces, surround it with double quotes.

Remote Shutdown

XP PRO has a lot of fun utilities. One of the most useful ones I have found to date is the ability to remotely reboot a PC. There are 2 ways of doing this. You will need to have admin access to the PC to preform these actions. That being said, here is the first way to do it:

Right click my computer, choose manage.
Highlight the Computer Management (Local) then click on Action, choose connect to another computer.
In the window that opens fill in the machine name of the PC you want to connect to and click ok.
Once connected right click on Computer Management (Remote machine name) and choose properties.
Go to the "Advanced" tab and click the Settings button under Start up and recovery.
Click on the Shutdown button.
Under action choose what you want to do (you can log off current user, shut down, restart, or power down. you can also choose if you want to force all applications to close, close hung apps, or wait for all apps to close by themselves).

The second way... Remember dos... that good old thing. Open up a command prompt and enter in the following:

%windir%\System32\shutdown.exe -r -m \\Machinename. The command prompt has more switches and options. I highly suggest using shutdown.exe /? to see all the posibilities.

Speed up your Bandwidth

Windows uses 20% of your bandwidth Here's how to Get it back

A nice little tweak for XP. Microsoft reserve 20% of your available bandwidth for their own purposes (suspect for updates and interrogating your machine etc..)

Here's how to get it back:

Click Start-->Run-->type "gpedit.msc" without the "

This opens the group policy editor. Then go to:


Local Computer Policy-->Computer Configuration-->Administrative Templates-->Network-->QOS Packet Scheduler-->Limit Reservable Bandwidth


Double click on Limit Reservable bandwidth. It will say it is not configured, but the truth is under the 'Explain' tab :

"By default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a connection, but you can use this setting to override the default."

So the trick is to ENABLE reservable bandwidth, then set it to ZERO.

This will allow the system to reserve nothing, rather than the default 20%.

I have tested on XP Pro, and 2000
other o/s not tested.

Difference between DVD-R, DVD+R, DVD-RW, etc

The difference between DVD-R, DVD+R, DVD+RW and DVD-RW explained

There's DVD+R, DVD+RW, DVD-R, DVD-RW, and even DVD-ROM! So what's the difference between all of these different names, aren't all DVDs the same? Well, it's not quite that simple.

Let's first start with the most obvious difference: some have R and some have RW. The "R" stands for readable, while the "W" stands for writeable.

The main difference between DVD-R and DVD-RW, or DVD+R and DVD+RW is that the R disc formats can only be written to once, and then it is only readable and can’t be erased for the rest of its digital life. While RW discs are can be written to and erased many times, they are both readable and writeable.

"R" discs are perfect if they are only needed to be written to once, such as giving some files to a friend or transferring them between PCs. "RW" discs have their strength in the ability to be used many times over, which is great for routine system backups, etc. And naturally, the RW discs are slightly more expensive than the R discs, but you'll have to decide if the trade offs are worth the money.

Now, onto the difference between DVD-R and DVD+R. As I just described above, DVD-R & DVD-RW are sister discs, the difference being one is writeable once, while the other is writeable multiple times. The same thing is true for DVD+R & DVD+RW. So the question is, what's the difference between the plus and minus?

In order to explain this we must take a trip back in time. When DVDs were first being developed, there was no industry standard. Multiple companies were competing to develop what they hoped would be the dominant form of the future.

The DVD-R DVD+R difference can easily be summarized by the following:

* The DVD-R/RW standard was developed by Pioneer, and is used primarily by Apple and Pioneer. These "minus" discs can only be written to in one layer on the discs surface. In addition, this format is supported by the DVD forum, but is in no way an industry standard. DVD-R/RW discs are cheaper than the "plus" format.
* The DVD+R/RW format is supported by Philips, Dell, Sony, HP, and Mcft. These discs can be written to in multiple layers, giving them slightly better and more disc storage than the "minus" format. Because of this additional capacity, they are slightly more expensive than "minus" discs.

A couple final things to clear up is the difference between DVD-ROM and DVD+RW, or the other DVD formats I mentioned above. The DVD-ROM drive can only read DVDs, while the other DVD drives can read and write data to DVDs.

And naturally the DVD+RW CD+RW difference can be explained by the "DVD" or "CD" prefix. DVDs, on average, can store up to 4.7 GB of data, while a CD can only store about 700 MB of data, or about 15% of a DVD's capacity. While CDs are slightly cheaper, in my opinion, the benefits of DVDs are much greater.

So now that you've learned about the difference between DVD-R, DVD+R, DVD-RW, DVD+RW, and even DVD-ROM, which one is right for you? The easiest way to determine which is more beneficial is to watch the industry trends. A few years ago all pre-built computers were shipping with DVD-ROM drives. Today, most PCs have a burnable DVD drive.

I feel that the benefits of having a burnable DVD drive far outweigh any additional costs. They store much more data, and they are ideal for storing your home movies to watch on your DVD player.

My advice is to look at DVD burners that support all of the major formats I've mentioned above, DVD-R, DVD+R, DVD-RW, and DVD+RW. While a DVD drive that supports all of these formats may be slightly more expensive, it will allow you to use any type of DVD disc to burn to, and you'll be protected from any industry shifts to one format or the other.

Tips for Avoiding virus infections

User's guide to avoiding virus infections
Keeping an eye out for viruses


Computer viruses are everywhere! This guide will show you how to stay alert and how to avoid getting infections on your computer. Having an updated virus scanner is only a small part of this, there are many ways that you can prevent having viruses other than a virus scanner, as it will not always save you.


Types of viruses
There are many type of viruses. Typical viruses are simply programs or scripts that will do various damage to your computer, such as corrupting files, copying itself into files, slowly deleting all your hard drive etc. This depends on the virus. Most viruses also mail themselves to other people in the address book. This way they spread really fast and appear at others' inboxes as too many people still fall for these. Most viruses will try to convince you to open the attachment, but I have never got one that tricked me. In fact, I found myself emailing people just to make sure they really did send me something. It does not hurt to be safe.


Worms
Worms are different type of viruses, but the same idea, but they are usually designed to copy themselves a lot over a network and usually try to eat up as much bandwidth as possible by sending commands to servers to try to get in. The code red worm is a good example of this. This worm breaks in a security hole in Microsoft IIS (Internet Information Server) in which is a badly coded http server that, despite the security risks, a lot of people use it. When the worm successfully gets in, it will try to go into other servers from there. When IceTeks was run on a dedicated server at my house, there was about 10 or so attempts per day, but because we ran Apache, the attempts did not do anything but waste bandwidth and not much as I had it fixed a special way. Some worms such as the SQL slammer will simply send themselves over and over so many times that they will clog up networks, and sometimes all of the internet. Worms usually affect servers more than home users, but again, this depends on what worm it is. It is suspected that most worms are efforts from the RIAA to try to stop piracy, so they try to clog up networks that could contain files. Unfortunately, the RIAA have the authority to do these damages and even if caught, nothing can be done.


Trojans
Trojans are another type of virus. They are simply like a server in which enables hackers to get into and control the computer. A trojan such as Subseven can enable a hacker to do various things such as control the mouse, eject the cd-rom drive, delete/download/upload files and much more.


MBR virues
Boot sector viruses are another type, they are similar to file viruses, but instead they go in the boot sector and can cause serious damage when the computer is booted, some can easily format your drive simply by booting your computer. These are hard to remove.


Most viruses have various characteristics. For example, a worm can also be a trojan and also infect the boot sector. It all depends on how the virus is written and what it is designed to do. That's why there are not really strong structured categories, as they can easily mix one in the other.


Know the potentially dangerous files
Like any other files, viruses must be opened in order to do something. Most viruses come through e-mail as an attachment. Some will make it look like it's someone you know, and it will try to convince you to open an attachment. Never open attachments at any cost! Some viruses will infect files in programs, so opening a program will actually open the virus, maybe the same one, or another part of it.


All files have what is called an extension; This is the 3 last letters after the last period. For example, setup.exe has a file extension of .exe.


Extensions to watch out for are .exe .com .bat .scr .pif .vbs and others, but these are the most seen. .exe .com .bat .pif and .scr are valid extensions for executables. A virus writer will simply rename it to one of these and it will work the same way. .pif is a shortcut to an ms-dos program and will have the ms dos icon, but will still execute whatever code is in it, so an .exe can be renamed to .pif and be run the same way. .bat is a batch file, which can contain instructions to do various file activities, but again, a .exe can be renamed to .bat and it will execute it! .vbs is a visual basic script. For some reason, Microsoft provides this scripting language along with the scripting host to make it more convenient to design and write viruses quickly and easily, I've never seen another use for this scripting language other than for writing viruses. There are programs that are written with that language, but it is compiled into an exe. Exe is the usual extension for programs, you would not have a software CD install a bunch of vbs files all over!


Bottom line is, if you don't know what a file is just don't open it. Some viruses will sometimes be named a way as to mask the real file extension to make it look like a harmless file such as a image file. This is easily noticed, but can still be missed. Simply don't open unexpected files.


If you get something that appears like something legit, just ask the person it came from if they sent it. Most viruses use a friend's address to make it look like it comes from them. The virus does this by using the person's address when sending itself to the address book contacts.


Downloads
Email is not the only way to get viruses; P2P (file sharing programs such as kazaa, winmx, direct connect etc) is also another way to get viruses.


When downloading programs, the main thing to watch out for is the file size. If you are downloading a program that you expect to be rather large such as a game, don't grab a file that is 10KB, since it's most likely a virus. However, I've been caught with a virus even with large files, so file size is not the only thing to watch, as an exe is still valid even if junk is added at the end, so a 64KB virus will still function even if it is turned into 650MB.


Icons are something to look for too, fortunately, virus writers don't take time to put icons. If your download should be a setup file, you should see the icon of a setup file. If it's just the blank icon that typical plain or corrupted exes have, don't open it.


Another thing to do, which should be obvious, is to scan the file for viruses using updated virus definitions. But don't rely on only your virus scanner, as they are not perfect, and if the virus has not been reported to them yet, they won't know to create a definition for it!


Changing settings to stay safe
If you do open a virus, you want to avoid it going to all your friends. The simplest thing to do is to NOT use the windows address book. It is easy for viruses to get through and Microsoft is not doing anything about it. Just don't use it. Put them in spreadsheet or even better write them down somewhere. Don't use the address book.


Another "feature" to avoid is the auto preview. Some viruses can attempt to open themselves just by opening the email. There are security holes in Microsoft mail programs that allow this. In Microsoft Outlook, click on the view menu and remove auto preview. You need to do this for every folder, but the inbox is most important. In Outlook Express, click on the view menu and go to layout. In the dialog box, you will see a check box for show preview pane. Uncheck it and click ok.


Another thing you should change, especially if you download a lot, is the option that allows you to view the file extension. In Win98, go in any folder, click on view then folder options and choose the view tab and where it says hide file extension for known types, uncheck it. In win2k, it is the same process, but instead, go in the control panel and open the folder options icon.


Avoiding server worms
Some viruses, mostly worms, can exploit through servers and affect other servers from servers that have been infected. A good example is the SQL slammer. This was a worm that affected SQL servers run by Microsoft IIS and Microsoft SQL Server. Once the worm gets in, that particular server starts trying to find more exploitable driving internet connections to a halt in the process. Servers running Apache were unaffected by that, except for the many hits to try to get in. IceTeks received about 100 hits per day when it was run on a dedicated home server. Most hits came from major ISPs and other big websites that had no clue they were still affected.


The simple solution to avoid these types of viruses is to NOT use Microsoft based server software for your server, especially if it is a public server. The operating system is also crucial, but the actual server software is much more. Apache, which is free, is much more secure than Microsoft based server programs such as IIS. IIS may be easier to understand and administer, but it saves a lot of hassle to learn how to use Apache. IIS has a large number of vulnerabilities, such as the ability to gain access to cmd.exe and basically delete the whole drive by doing a ../ request in the address bar. These don't require viruses, but simply commands, but there are worms written to automatically make these commands. The code red does this.


Removing a virus
The best way to do this is to do a clean install. However, depending on how bad the virus is, a simple clean install won't remove it. So to be extra sure, you'll want to do a low level format. This is especially true of you got a boot sector virus, as even repartitioning and formatting won't quite remove it, but sometimes you can get away with an fdisk /mbr, but not all the time. here are various removal tools for viruses, it is good to use them and see if they work, but proceeding with the clean install is recommended. You never know if the virus is completely removed by deleting files you suspect are infected. Some viruses such as the Bugbear will close anti virus programs and other programs to make it hard and annoying to figure out what to do. A clean install is the best way to ensure that it's gone for good.

Viruses are out there, don't be one of the many infected ones! Stay alert and stay safe! Don't open unexpected files, regularly update your virus definitions and scan downloaded files!

Many Useful Tips you never heard about XP

Some Tips And Tricks For Your Windows XP

STOP NOISE IN COPYING AUDIO CD
When using 3rd party burning software (eg, Nero Burning Rom) to copy audio CD,some noise may be heard at the end of each track. To prevent this,try the following method:
1. Enter System Properties\device manager
2. Select IDE ATA/ATAPI controllers
3. Double click on thee CD writer IDE channel
4. Select advance setting
5. Change the transfer mode to 'PIO Only'
6. Restart Computer

DISABLING THE 'UNSIGNED DRIVER' DIALOGS
This option wll disable the screen wich keeps popping up when you try to install 'digitally unsigned drivers'. Normally you can choose to continue the install anyways, but I have had situations where you cannot continue the install.. very annoying.. This is how to fix it:
Click Start - Run
then type: gpedit.msc
then hit enter.
Browse the folder tree to the following location:
User Configuration - Administrative Templates - System
now right-click Code signing for Device drivers and select Properties.
On the Settings tab, either select
- enable, and then select ignore from the appearing listbox..
- or click the disable option. Click apply and Ok and your set!
Alternatively especially for XP Home users:
Open "System" properties (Windows key + pause or Right click 'My Computer' - properties or Control Panel - System).On the Hardware tab click the "Driver Signing" button. In the dialogue that comes up choose "Ignore" to install the new driver anyway.

DMA MODE ON IDE DEVICES VIEWS
Just like Windows 2000, Windows XP still fails to set the DMA mode correctly for the IDE device designated as the slaves on the primary IDE and secondary IDE channels. Most CD-ROMS are capable of supporting DMA mode, but the default in XP is still PIO. Setting it to DMA won't make your CD-ROM faster, but it will consume less CPU cycles. Here's how:
1. Open the Device Manager. One way to do that is to right click on "My Computer", select the Hardware tab, and Select Device Manager.
2. Expand "IDE ATA/ATAPI Controllers" and double-click on "Primary IDE Channel"
3. Under the "Advanced Settings" tab, check the "Device 1" setting. More than likely, your current transfer mode is set to PIO.
4. Set it to "DMA if available".
Repeat the step for the "Secondary IDE Channel" if you have devices attached to it. Reboot.

RESTORING MEDIA PLAYER
To restore Windows Media Player insert the the XP CD into the CD drive (if it autostarts click exit). Open a command window and type the following :
rundll32.exe setupapi,InstallHinfSection InstallWMP7 132 c:\windows\inf\wmp.inf

RESTORING ACCESS TO CD ROM'S
If you removed CD Burning software, or for some other mystical reason, can not longer access your CD ROM's, in most cases following registry keys needs to be deleted: Locate and delete the UpperFilters and LowerFilters values under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

DELETING THE INDEX.DAT
Del "C:\Documents and Settings\aeon\Local Settings\Temporary Internet Files\Content.IE5\index.dat"

CONTROL PANEL ON THE DESKTOP.
On The Desktop, Right Click Your Mouse Then Choose "New | Folder". Name The Folder As "ControlPanel. {21EC2020-3AEA-1069-A2DD-08002B30309D}" Without The "Quote Things. And Now You Can Access The Control Panel More Faster Then Before.

CHANGING INTERNET EXPLORER ICON NAME.
Open Registry Editor Then Go To : "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\CLSID". You Can See A Few Key Below It.

Now Go To This Key {871C5380-42A0-1069-A2EA-08002B30309D}, Double Click At The Default Value On The Right, Enter Whatever Name You Like.

REMOVING USERNAME IN THE STARTMENU
Open Registry Editor Then Go To : "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer".
On The Right, Make A New Entry With Right Click On Your Mouse Then Choose "New | DWORD Value" Change The Entry's Name Into "NoUserNameInStartMenu", Double Click In The New Entry And Fill The "Value Data" With "1". Press OK, Exit From The Registry Editor. Restart Your Computer.

INTERNET EXPLORER LIGHTING-FAST STARTUP.
Isn't it annoying when you want to go to a new website, or any other site but your homepage, and you have to wait for your 'home' to load? This tweak tells Internet Explorer to simply 'run', without loading any webpages. (If you use a 'blank' page, that is still a page, and slows access. Notice the 'about:blank' in the address bar. The blank html page must still be loaded..). To load IE with 'nothing' [nothing is different than blank]:
1. Right-click on any shortcut you have to IE
[You should create a shortcut out of your desktop IE icon, and delete the original icon]
2. Click Properties
3. Add ' -nohome' [with a space before the dash] after the endquotes in the Target field.
4. Click OK
Fire up IE from your modified shortcut, and be amazed by how fast you are able to use IE!

INTERNET EXPLORER SPEED UP.
Edit your link to start Internet Explorer to have -nohome after it. For Example: "C:\Program Files\Internet Explorer\IEXPLORE.EXE" -nohome
This will load internet explorer very fast because it does not load a webpage while it is loading. If you want to go to your homepage after it is loaded, just click on the home button.

SPEED UP BROWSING WITH DNS CATCH.
when you connect to a web site your computer sends information back and forth, this is obvious. Some of this information deals with resolving the site name to an IP address, the stuff that tcp/ip really deals with, not words. This is DNS information and is used so that you will not need to ask for the site location each and every time you visit the site. Although WinXP and win2000 has a pretty efficient DNS cache, you can increase its overall performance by increasing its size. You can do this with the registry entries below:
************begin copy and paste***********
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]
"CacheHashTableBucketSize"=dword:00000001
"CacheHashTableSize"=dword:00000180
"MaxCacheEntryTtlLimit"=dword:0000fa00
"MaxSOACacheEntryTtlLimit"=dword:0000012d
************end copy and paste***********
make a new text file and rename it to dnscache.reg. Then copy and paste the above into it and save it. Then merge it into the registry.

START IEXPLORER WITH EMPTY BLUE SCREEN.
Set your default page to about:mozilla and IE will show a nice blue screen upon startup.

SPEED UP DETAILED VIEW IN WINDOWS EXPLORER.
If you like to view your files in Windows Explorer using the "Details" view here is a tweak to speed up the listing of file attributes: Viewing files in Windows Explorer using the "Details" mode shows various attributes associated with each file shown. Some of these must be retrieved from the individual files when you click on the directory for viewing. For a directory with numerous and relatively large files (such as a folder in which one stores media, eg: *.mp3's, *.avi's etc.)

Windows Explorer lags as it reads through each one. Here's how to disable viewing of unwanted attributes and speed up file browsing:
1. Open Windows Explorer
2. Navigate to the folder which you wish to optimize.
3. In "Details" mode right click the bar at the top which displays the names of the attribute columns.
4. Uncheck any that are unwanted/unneeded.
Explorer will apply your preferences immediately, and longs lists of unnecessary attributes will not be displayed. Likewise, one may choose to display any information which is regarded as needed, getting more out of Explorer.

WEB PAGES SLOWS DOWN, FIX.
The tweak is simple. Beside the QoS and others around the Internet for the new XP OS, I found out that native drivers sometimes slow you down (cable and xDSL users). So if you have applied all tweaks and you are still having slow downs try reinstalling your NICs drivers. The difference is noticeable. My web pages now load almost instantly where they used to take even a minute!

FIX IE 6 SLOWDOWNS AND HANGS.
1. Open a command prompt window on the desktop (Start/Run/command).
2. Exit IE and Windows Explorer (iexplore.exe and explorer.exe, respectively, in Task Manager, i.e - Ctrl-Alt-Del/Task Manager/Processes/End Process for each).
3. Use the following command exactly from your command prompt window to delete the corrupt file:
C:\>del "%systemdrive%\Documents and Settings\%username%\Local
Settings\Temporary Internet Files\Content.IE5\index.dat"
4. Restart Windows Explorer with Task Manager (Ctrl-Alt-Del/Task Manager/Applications/New Task/Browse/C:\Windows\explorer.exe[or your path]) or Shutdown/Restart the computer from Task Manager.

SPEED UP WEB BROWSING.
Iv'e personally found a dramatic increase in web browsing after clearing the Windows XP DNS cache. To clear it type the following in a command prompt: ipconfig /flushdns.

ALLOW MORE THAN 2 SIMULTANEOUS DOWNLOADS ON IEXPLORER 6.
This is to increase the the number of max downloads to 10.
1. Start Registry Editor (Regedt32.exe).
2. Locate the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
3. On the Edit menu, click Add Value , and then add the following registry values:
"MaxConnectionsPer1_0Server"=Dword:0000000a
"MaxConnectionsPerServer"=Dword:0000000a
4. Quit Registry Editor.

IPV6 INSTALLATION FOR WINDOWS XP.
This protocol is distined to replace the Internet Protocal Version 4 used by Internet Explorer it uses hexadecimal ip addresses instead of decimal example (decimal ip 62.98.231.67) (hexadecimal IP 2001:6b8:0:400::70c)
To install To install the IPv6 Protocol for Windows XP:
Log on to the computer running Windows XP with a user account that has local administrator privileges. Open a command prompt. From the Windows XP desktop, click Start, point to Programs, point to Accessories, and then click Command Prompt. At the command prompt, type: ipv6 install
For more information on IPv6, visit the site below:

ANOTHER WAY TO FIX IEXPLORER 6 SLOW PAGES LOADED.
Here's an easier way to get to index.dat file as addresse in another tweak submitted here.
1. click on Internet Explorer
2. go to to your root dir (usually C:)
3. open Documents and Settings folder
4. open "your username folder"
5. open UserData
6. **close IE if you have it open**
rename index.dat to index.old
logoff and log back on (don't need to restart) open up IE and go to a web page or site that always seemed to load slowly. It should load a lot more quickly now. NOTE. Always rename or backup .dat or other system files before deleting.

EASY WAY TO ADD THE ADMINISTRATOR USER TO THE WELCOME SCREEN.
Start the Registry Editor Go to:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon \ SpecialAccounts \ UserList \
Right-click an empty space in the right pane and select New > DWORD Value Name the new value Administrator. Double-click this new value, and enter 1 as it's Value data. Close the registry editor and restart.

DRIVE ICONS.
To set the icon of any drive (hard disk, cd rom or anything else) with a letter (C:\ etc.), run REGEDIT (Start -> Run -> regedit)
Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer
If one doesn't already exist, create a new KEY called "DriveIcons". Under this key, create a new key with the letter of your drive. I.e. C for your C:\ drive.
To change the icon for that drive, create a key inside that one called DefaultIcon and set the path of (Default) to the location of your icon
eg C\DefaultIcon\ then (Default) = D:\Documents\C Drive Icon.ico
To change the name of that drive, create a key in the drive letter one (eg C\) called DefaultLabel and set the (Default) to what you want the drive to be called. This is useful if you want to assign a long name to the floppy drive.

CHANGING OEM REGISTRATIONS.
Have you used someone's new Hewlet Packard with their OEM version of Windows XP? You've seen that HP has their own icon in the Start Menu, underneath Run, that goes to their Help Site. Now, you can have your icon that does anything you want (website, program, etc) and says anything you want. Basically, you are "branding" Windows XP (Home or Pro), great for if you are a computer builder and sell them, or you just want to make Windows XP your own. It involves Regedit.
1. Start up Notepad and creat a new registry file (*.reg) and copy and paste the following into it:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\CLSID\{2559a1f6-21d7-11d4-bdaf-00c04f60b9f0}]

"Attributes"=dword:00000000
2. Edit where it says YOUR ICON HERE to a path to an icon (ex. c:\\icon.ico), it must be 24x24 pixels and in *.ico format. Use double back slash for path names.
3. Edit both places where it says YOUR TITLE HERE to what you want it to say in the Start Menu (ex. Elranzer Homepage).
4. Edit where it says YOUR FUNCTION here to what you want it to do when you click it, it can be anything... your website, a local HTML document, a program, a Windows funtion, whatever your imagination can provide (ex. http://www.shareordie.com).
5. Save this file as brand.reg, double-click it to enterin your information, and refresh Explorer (log off/on) to see it in the Start Menu!! This works in both Home and Professional (and probably 64-Bit Professional) Editions!

ORIGINAL WALLPAPERS.
This is more of a fun tweak than it is useful. Go to run, type regedit press ok. when that comes up go to HKEY_CURRENT_USER>Control Panel>Desktop
Now find the orginalwallpaper, right click and select modify.In the text box type the path to the file you want to be your orginal desktop wallpaper.

DELETING My eBooks AND SPECIALS FOLDER IN MY DOCUMENTS.
Click Start, then Run and type: regsvr32 /u mydocs.dll
then delete them.

DISABLE WINDOWS PICTURE AND FAX VIEWER.
By default, Windows XP opens all picture files (gif,jpg,...) with the included Windows Picture and Fax Viewer no matter what other picture viewers you have installed. To disable the Windows Picture and Fax Viewer, unregister shimgvw.dll. This can be done from command prompt: regsvr32 /u shimgvw.dll

REMOVE PAST ITEMS ICONS IN TASKBAR.
Some times When you check your TasKbar properties or when you hide or unhide icons you can see old icons from Uninstalled or old programs you dont have anymore. This Tweak will help you how to get rid of this problem Thanks to leobull of Xperience.or How To clear the Past Items or Icons list in the TaskBar, perform the following steps:

2.Delete the IconStreams and PastIconsStream values
3.Open Task Manager, click the Processes tab, click Explorer.exe , and then click End Process .
4.In Task Manager, click File , click New Task , type explorer , and then click OK .

LOCKING COMPUTERS.
To lock a computer in XP, as you probably know, you press "L" while holding down "Windows Logo" key on your keyboard. However, if you would like to lock a computer remotely, for example via "Remote Administrator", you don't have this ability. What you can do instead, is to create a shortcut on remote computer's desktop where Target %windir%\System32\rundll32.exe user32.dll,LockWorkStation Start In %windir%

ADMINISTRATOR IN WELCOME SCREEN.
When you install Windows XP an Administrator Account is created (you are asked to supply an administrator password), but the "Welcome Screen" does not give you the option to log on as Administrator unless you boot up in Safe Mode.
First you must ensure that the Administrator Account is enabled:
1 open Control Panel
2 open Administrative Tools
3 open Local Security Policy
4 expand Local Policies
5 click on Security Options
6 ensure that Accounts: Administrator account status is enabled Then follow the instructions from the "Win2000 Logon Screen Tweak" ie.
1 open Control Panel
2 open User Accounts
3 click Change the way users log on or log off
4 untick Use the Welcome Screen
5 click Apply Options
You will now be able to log on to Windows XP as Administrator in Normal Mode.

BUGFIXES.
This is a strange bug in Windows XP Pro but it can and does happen to everyone. When you open the My Computer screen and your Documents folder is missing but all the other users folders are there try this tweak.
STEP 1:
START > RUN > REGEDIT > HKEY_LOCAL_MACHINE / Software / Microsoft / Windows / Current Version / Explorer / DocFolderPaths
Once you click the DocFolderPaths folder you should see all the user's folders.
STEP 2:
Add a new string value
Value Name: your user name
Value Data: the path to your docs folder ( ex. C:\Documents and Settings\your docs folder )
Exit Registry editor and open my computer, your docs folder should now be visable.

MOUSE POINTERS.
It seems that even without pointer precision disabled, the mouse under XP is still influenced by an acceleration curve. This is especially noticeable in games. To

completely remove mouse acceleration from XP, you will need to go into the registry and adjust the SmoothmouseXYCurve values. Here is how its done.
1. Click Start button
2. Select Run
3. Type 'regedit' in the open textbox
4. Open the tree 'HKEY_CURRENT_USER', select control panel, then select mouse
5. Right clicking, modify the SmoothMouseXCurve and SmoothMouseYCurve hexidecimal values to the following:
SmoothMouseXCurve:
00,00,00,00,00,00,00,00
00,a0,00,00,00,00,00,00
00,40,01,00,00,00,00,00
00,80,02,00,00,00,00,00
00,00,05,00,00,00,00,00
SmoothMouseYCurve:
00,00,00,00,00,00,00,00
66,a6,02,00,00,00,00,00
cd,4c,05,00,00,00,00,00
a0,99,0a,00,00,00,00,00
38,33,15,00,00,00,00,00
If done correctly, you will notice you are holding a markedly more responsive mouse.

HIDDEN WINDOWS XP ICONS.
Windows XP Pro and Home contains icons for folders and files that cannot normally be seen, you can select to view hidden files from the folder options menu, but there are still some that remain hidden.
You can set windows to view these files as normal hidden files, so that when you use the view hidden files and folders toggle from the folder options menu that these will be turned on/off along with the normal hidden files.
These files are usually system files and should not be altered/deleted unless you really know what you are doing, if you don't yet still wish to change them I might suggest that you create back-ups of your system first.
I will personally accept no responsibility for any damage caused by using this tweak. To view the hidden files you need to open up regedit, if you are not sure how to do this, select run from the start menu and type in 'regedit' without the apostrophe's. In the regedit window, expand out the groups by clicking on the '+' next to the name in the left hand column of regedit, and navigate to the below address.
HKEY_CURRENT_USER \SOFTWARE \MICROSOFT \WINDOWS \CURRENTVERSION \EXPLORER \ADVANCED
when you have clicked the advanced folder on the left pane, look down the list at the titles in the right hand pane, one of those titles is 'ShowSuperHidden'
double click the title and in the window that appears set the value to equal 1 to show the super hidden files and 0 to hide them.

XP HOME ADVANCED FILE PERMISSIONS.
This is actually an addition to my previous post entitled "Get XP Pro file security with XP Home". In the aforementioned post I outlined how to access
*Advance file Permissions* on NTFS file systems for XP Home simply by booting into *Safe Mode*, rt-clicking any file or folder, and navigating to the *Security tab*. This gives the user the ability to allow or deny read, write, execute, read & write, display contents, full-control, iheritance, and take ownership permissions, with many more options available to apply to different users and groups stored on the computer. Well, you don't have to do this in *Safe Mode* (XP Home). Although it is a little less intuitive, you can simply go to your command prompt - Start>All Programs>Accessories>Command Prompt. Now type "cacls" in the window (without the quotes). This gives you the ability to add, remove or modify file permissions on files and folders through the command prompt. Type "cacls /?" for help on different options and variables. You do not need to be in safe mode to use this so it makes it a little quicker than using the safe mode security tab GUI. Remember - this only applies to NTFS. Here also is a very useful link to find a lot of extras and tweaks straight from the horse's mouth - the Microsoft Resource Center. You will find a lot of very useful web-based extra's here, most of them left unknowing to the general public - such as, "Online Crash Analysis" - a site that looks like Windows Update but you can upload your crash "dump logs" (when you get those system or application crash error reports). Microsoft will then analyze the log file and tell you some more info about WHY the system crashed (ie. faulty hardware/software/conflicts, etc).

FLASHGET :BYPASSING 8 MAX SIMULTANEOUS JOBS.
Users of Flash get will notice that the maximum number of file splits is 8. This number can be increased by the tweak below:
1. Run regedit.
2. Navigate to [HKEY_CURRENT_USER\Software\JetCar\JetCar\General\]
3. Right Click -> Add String Value.
4. Name as MaxSimJobs -> Set the value as what ever number you want.
After a restart you should be able to download with more file splits.

OUTLOOK EXPRESS WINDOWS TITLE TWEAKS.
Change the window title of Outlook Express to anything you want!
In regedt32 and navigate to HKEY_CURRENT_USER\Identities\{EE383506-901D-43C6-8E40-9A61901DF7CC}\Software\Microsoft\Outlook Express\5.0. Add a new string key called WindowTitle and make its value the desired window title. Then close the registry editor, and restart Outlook Express (if it's running.) Your new title now shows up in the title bar!

WINDOWS MEDIA PLAYER 9.
When installing WMP 9 it leaves a watersign on your desktop. You can easily remove this with: regedit:
HKey_Local_Machine\SOFTWARE\microsoft\system certificates\CA\certificates\FEE449EE0E3965A5246F00E87FDE2A065FD89D4
HKey_Local_Machine\software\microsoft\system certificates\ROOT\certificates\2BD63D28D7BCD0E251195AEB519243C13142EBC3
Remove both lines and restart computer.

CHANGING THE WINDOWS MEDIA PLAYER TITLEBAR.
This is a per-user tweak. Open RegEdit.
Browse to the following key:
HKEY_USERS\S-1-5-21-xxxxxxxxx-xxxxxxxxx-xxxxxxxxxx-xxxx\Software\Policies\Microsoft\WindowsMediaPlayer
(the x's will vary from computer to computer , it's the key without the "_Classes" at the end) Create the following String, "TitleBar" , the value of this will now become the TitleBar of Windows Media Player.

AUTO DELETE TEMPORARY FOLDER.
First go into gpedit.msc
Next select -> Computer Configuration/Administrative Templates/Windows Components/Terminal Services/Temporary Folder
Then right click "Do Not Delete Temp Folder Upon Exit"
Go to properties and hit disable. Now next time Windows puts a temp file in that folder it will automatically delete it when its done! Note from Forum Admin: Remember, GPEDIT (Group Policy Editor) is only available in XP Pro.

CLEANUP STARTUP ITEMS IN MSCONFIG.
Do you ever uninstall programs and they are still listed under startup items in msconfig? Personally, I found myself with 30 such items from old installs. Microsoft leaves you no way to clean up this list, but have no fear, I have figured it out for you.
1. Open MSconfig and click on the startup items tab
2. Open Regedit and naviate to HKLM/Software/Microsoft/Sharedtools/MSconfig/startupreg
3. Compare the list of registry keys under startup reg with their counterparts in msconfig.
4. Delete the keys which are no longer valid.
5. Voila! You've cleaned up msconfig.

REMOVING SERVICES DEPENDENCIES.
This will allow you to disable a service or uninstall it from your system without effecting another service that depends on it. Here's how you do it
1. After you have set your services the way you want them and you have disabled/uninstalled something that another services depends on, run "regedit"
2. Under HKEY_LOCAL_MACHINE\System\find the service that will not function, do to another service being disabled/uninstall (found in ControlSet001\Services, ControlSet002\Services, and CurrentControlSet\Services)
3. Once you have found the service right-click on the string value, "DependOnService,"and modify
4. You should now see a list of services that it is dependent on. Simply delete the service that you have disabled/uninstalled
5. Restart your computer and your ready to go Disclaimer REMEMBER TO BACKUP YOU REGISTRY FIRST I'm not totaly sure if this will have any negative effects on your system. I used this method after uninstalling "Netbios over Tcpip" from my system completely, so that my Dhcp service would function and I have had NO negative effects on my system.

ANOTHER WAY TO DELETE HIDDEN DEVICES.
You can view and delete or modify hidden devices by:
1. Openning Device Manager. (I usually right-click on My Computer, select Properties, select the Hardware tab, then select Device Manager.)
2. Select View and check "Show hidden devices"
3. Hidden devices will appear below with the others and can be modified.

HOW TO GET "My Briefcase" IN WINDOWS XP.
go to C:\WINDOWS\system32\dllcache. look for a file named "syncapp".
double click it. an icon should appear on your desktop that says "My Briefcase". double click it. it will come up with this window that tells you how to use it.

TURN NUMLOCK ON AT LOGON.
NumLock does not toggle on by default (system-wide), even if you have it set in your PC's BIOS, because of XP's multi-user functionality. Guess Microsoft doesn't know everyone actually turns it on, which should be reason enough for what acts as "default"...
Anyway, you can hack the Windows Registry to change this behavior, or run a script at logon to turn NumLock on.
1. To enable NumLock through the Registry:
* Open Windows' Registry Editor (START > RUN, type "REGEDIT").
*. Navigate to HKEY_USERS\.Default\Control Panel\Keyboard.
*. Change the value for InitialKeyboardIndicators from 0 to 2.
2. To enable NumLock using a script, see this MS Knowledgebase article for complete instructions:
CODE
http://support.microsoft.com/directory/article.asp?ID=KB;EN-US;Q262625

Option 1 is the quicker method, but if you have more than one user on your system and one or more don't want NumLock on (stranger things have been known of), then option 2 is the way to go since it allows you to only attach the script to specific users.

FREE DISK SPACE BY DELETING RESTORE POINTS.
Start button-all programs-accessories-system tools-cleanup-more options. You will have the option of deleting your restore points.When your done creat one
restore point as a back up.

HOW TO REAL GET RID OF UNNECESSARY SOFTWARE
to uninstall things like msn messenger and other hidden installs thru add remove programs, do this: find sysoc.inf (you might have to enable "show hidden files" and "show hidden/protected system folders" in explorer) and open it in notepad replace all ",hide" with "," (both with out quotes) which is easiest to do with the replace all command under edit then in add/remove programs under add/remove windows compnents and whole new list of things to uninstall and add are now listed (such as internet explorer)

HAVING PROGRAMS RUN WHEN WINDOWS LOADS SLOWS DOWN YOUR STARTUP.
There are two ways do disable programs that may be in your startup (like icq, messanger,) The easiest is to do the following:
1. start --> run --> msconfig
2. Click on the "startup" tab (furthest right)\
3. Unclick any items you don't want to load when windows starts.
The second is by deleting registry entrys, this can be done the following way:
1. Start --> run --> regedit
2. Navigate to : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
3. Delete any entry's that you don't want to load up

TURN OFF INDEXING TO SPEED UP XP.
Windows XP keeps a record of all files on the hard disk so when you do a search on the hard drive it is faster. There is a downside to this and because the computer has to index all files, it will slow down normal file commands like open, close, etc. If you do not do a whole lot of searches on your hard drive then I suggest turnning this feature off:
1. Control Panel
2. Administrative Tools
3. Services
4. Disable Indexing Services

HALF LIFE AND WINDOWS XP.
1. How to recover from incompatible drivers
Before you install new drivers set a system restore point. Start>All programs>Accessories>system tools>system restore
After your new drivers don't work reset your computer. Press F8 repeatedly as soon as the BIOS screen disappears, and before the Windows XP screen appears. Select safe mode. Use system restore again to undo your mess.
2. Video Drivers
The NVidia drivers that come with XP do not allow you to run Half Life in OpenGL. Update to the newest drivers.
Despite the fact that they are not official drivers, 22.50 was the only set which worked
3. Sound Drivers
Use windows update to update Creative drivers.
4. Fixing screen flicker
Windows XP defaults to 60Hz for games. A fix is available here:
CODE

6. Mouse
You can improve your mouse smoothness for games.
Control panel>mouse>hardware>properties>advanced
Change the sample rate to a higher one, eg. 200

REGISTRY METHOD FOR REMOVING STARTUP ITEMS.
I prefer to use MSCONFIG selective startup to troubleshoot. To remove entries for good, open the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RUN and HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RUN
Delete entries of unwanted startup daemons and tray procedures.

DISPLAY MESSAGE ON STARTUP.
Start regedit, if you are unfamiliar with regedit please see our FAQ.
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Modify the key legalnoticecaption with what you want to name the window.
Modify the key legalnoticetext with what you want the window to say. Restart.

REMOVE THE DEFAULT IMAGE VIEWER IN WINDOWS ME/XP.
This tweak works in Windows Me/XP, I have not try it in Windows NT/2000 yet, because i don't have that OS, you can try it if you have.
*This tweak does not work in Windows 95/98
To remove the Windows default Image Viewer, first:
Click Start Menu
Select Run menu
Type "cmd", (for Windows Me, type "command")
Then type "regsvr32 /u shimgvw.dll" to unregister this dll. This will stop it from previewing any picture that it support, e.g. JPEG, Bitmap, GIF....
* Before perform this tweak, make sure that you have the alternative Image Viewer installed in you windows e.g. ACDsee, FireGraphics... because once you do this tweak without that application, you can't open and view your image anymore! So, to undo it, type "regsvr32 shimgvw.dll" in command prompt.

SPEED UP BOOT BY DISABLING UNUSED PORTS.
You may have tried many tweaks like modifying windowsXP start-up applications, prefetches, unload DLLs method,etc. And yes those methods do work for me.
I have just accidentally found out another way to give you an extra boost in windowsXP's boot performance. This is done by disabling your unused devices in
Device Manager. for example, if you don't have input devices that are connected to one of your USBs or COM ports, disabling them will give you an extra perfromance boost in booting. Go to Control Panel -> System -> Hardware tab -> device manager Disable devices that you don't use for your PC and then restart.

CLEAR UNWANTED ENTRIES FROM ADD/REMOVE PROGRAMS.
Run the Registry Editor (REGEDIT).
Open HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows\ CurrentVersion\ Uninstall Remove any unwanted keys under "Uninstall."

CLICKING * .AVI FILES ON EXPLORER CAUSING 100% CPU USAGE.
Well windows seem to have a REALLY big problem when it comes to reading AVI files. It seems that when you click on an AVI file in explorer, it'll try to read the entire AVI file to determine the width,height, etc. of the AVI file (this is displayed in the Properties window). Now the problem with Windows is that if you have a broken/not fully downloaded AVI file that doesnt contain this info, Windows will scan the entire AVI file trying to figure out all these properties which in the process will probably cause 100% CPU usage and heavy memory usage. To solve this problem all you have to do is the following:
1. Open up regedit
2. Goto HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shellex\PropertyHandler
3. Delete the "Default" value which should be "{87D62D94-71B3-4b9a-9489-5FE6850DC73E}"
Voila! Please not that this will no longer provide you with the windows properties displaying the AVI file information such as width, height, bitrate etc. But its a small price to pay for saving you resources.
NOTE: Please use caution when using regedit. Improper usage may cause windows to behave imcorrectly. Also, I cannot be held resposible. Backup your registry first.

CD ROM STOPS AUTOPLAYING/AUTORUN.
And the AutoPlay Tab has disappeared in My Computer, Devices With Removable Storage, Right Click on CDROM, Properties.
Solution: The service: "Shell Hardware Detection" has been set to Manual or Disabled. Go to Control Panel, Administrative Tools, Services. Return this service to "Automatic".

SHUTDOWN XP FASTER 1.
Like previous versions of windows, it takes long time to restart or shutdown windows xp when the "Exit Windows" sound is enabled. to solve this problem you
must disable this useless sound. click start button then go to settings -> control panel -> Sound,Speech and Audio devices -> Sounds and Audio Devices -> Sounds, then under program events and windows menu click on "Exit Windows" sub-menu and highlight it.now from sounds you can select,choose "none" and then click apply and ok. now you can see some improvements when shutting down your system.

SHUTDOWN XP FASTER 2.
Start Regedit.
Navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control.
Click on the "Control" Folder.
Select "WaitToKillServiceTimeout"
Right click on it and select Modify.
Set it a value lower than 2000 (Mine is set to 200).

EASIEST WAY TO DELETE PREFETCH.
1. Open notepad.exe, type del c:\windows\prefetch\*.* /q (without the quotes) & save as "delprefetch.bat" in c:\
2. From the Start menu, select "Run..." & type "gpedit.msc".
3. Double click "Windows Settings" under "Computer Configuration" and double click again on "Startup" in the right window.
4. In the new window, click "add", "Browse", locate your "delprefetch.bat" file & click "Open".
5. Click "OK", "Apply" & "OK" once again to exit.
6. Reboot your computer.

SPEED UP MENU DISPLAY.
When using the start menu the you will notice a delay between different tiers of the menu hierarchy. For the fastest computer experience possible I recommend changing this value to zero. This will allow the different tiers to appear instantly. Start Regedit. If you are unfamiliar with regedit please refer to our FAQ on how to get started.
Navigate to HKEY_CURRENT_USER\Control Panel\Desktop
Select MenuShowDelay from the list on the right.
Right on it and select Modify.
Change the value to 0.
Reboot your computer.

16 COLOUR ICONS.
If you select 16bit mode for graphics your icons will revert to using 8bit (16 color) icons. Yuck! Change the following registry setting to:
[HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics] "Shell Icon BPP"="16" "Shell Icon Size"="32" Setting the BPP to 16bit will yield 65565 colors for icons.

DE-CRYPT ENCRYPTED FILES ON WINDOWS XP.

DUMP FILES TWEAK & DISABLE DR.WATSON.
"Dump file. A dump file stores data from memory during a system crash and can be helpful when diagnosing problems, but like a swap file, it can also expose a lot of sensitive, unencrypted data. To prevent Windows from creating the file, go to Control Panel | System. Click on the Advanced tab and then the Settings button on the Startup and Recovery pane. Set the drop-down menu under Write debugging information to (none). "Similarly, the debugging program Dr. Watson saves information when applications crash. To disable it, go to:
HKEY_local_machine\software\Microsoft\WindowsNT\CurrentVersion\ AeDebug and set the Auto string to 0. Then use Windows Explorer to go to Documents and Settings\All Users\Shared Documents\DrWatson. Delete User.dmp and Drwtsn32.log, the insecure logs the program creates." Heed related advice from 'microsoft' regarding 'Disable Dr.Watson' first before the preceding Dr. Watson advice (go Google search.) Back up with System Restore, and go ahead. As cautious as I am, I have gladly applied these tweaks, and followed related microsot advice on Dr. Watson.
