How do I delete an "undeletable" file?

Open a Command Prompt window and leave it open. Close all open programs. Click Start, Run and enter TASKMGR.EXE Go to the Processes tab and End Process on Explorer.exe. Leave Task Manager open. Go back to the Command Prompt window and change to the directory the AVI (or other undeletable file) is located in. At the command prompt type DEL where is the file you wish to delete. Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell. Close Task Manager.

Unregister Spyware DLL Files Manually

Warning: Unregistering spyware DLL files is difficult and risky. If you unregister the wrong DLL file, your computer may crash and important data may be lost. As a precautionary measure, please back up important files and set a System Restore point (click Start > All Programs > Accessories > System Tools > System Restore, and follow the on-screen instructions) or [Only registered and activated users can see links. ] with a trusted anti-spyware program to automatically detect spyware.
To start unregistering DLL files, you will need to follow these steps:

Open the Command Prompt window
Press the “Start” button on your taskbar and click on “Run” to start the “Run” tool. In the field, type “cmd” and press the “OK” button.
Locate the DLL file
After opening the Command Prompt window, locate the exact DLL path as shown on the screenshot below. Type “cd” in order to change the current directory, press the “space” button, enter the full path to the DLL file and press the “enter” button on your keyboard. If you want to display the contents of the directory, use the “dir” command.
Unregister the unwanted DLL
In the directory where you want to remove the DLL, type “regsvr32 /u [DLL_NAME]” and press the “Enter” button.
Unregistering succeeded
If the DLL was unregistered successfully, a confirmation message will be displayed.

If you want to undo the removal, you can perform it by typing “regsvr32″ without the /u key, just type “regsvr32 [DLL_NAME]” to undo the changes.

YES of course nothing is impossible but first we have to understand windows xp file system structure as given below.

WEP
Windows File Protection (WFP) prevents programs from replacing critical Windows system files. Programs must not overwrite these files because they are used by the operating system and by other programs. Protecting these files prevents problems with programs and the operating system.

WFP protects critical system files that are installed as part of Windows (for example, files with a .dll, .exe, .ocx, and .sys extension and some True Type fonts). WFP uses the file signatures and catalog files that are generated by code signing to verify if protected system files are the correct Microsoft versions. Replacement of protected system files is supported only through the following mechanisms:

•	Windows Service Pack installation using Update.exe
•	Hotfixes installed using Hotfix.exe or Update.exe
•	Operating system upgrades using Winnt32.exe
•	Windows Update

If a program uses a different method to replace protected files, WFP restores the original files. The Windows Installer adheres to WFP when installing critical system files and calls WFP with a request to install or replace the protected file instead of trying to install or replace a protected file itself.How the WFP feature works

The WFP feature provides protection for system files using two mechanisms. The first mechanism runs in the background. This protection is triggered after WFP receives a directory change notification for a file in a protected directory. After WFP receives this notification, WFP determines which file was changed. If the file is protected, WFP looks up the file signature in a catalog file to determine if the new file is the correct version. If the file is not the correct version, WFP replaces the new file with the file from the cache folder (if it is in the cache folder) or from the installation source. WFP searches for the correct file in the following locations, in this order:

1.	The cache folder (by default, %systemroot%\system3 2\dllcache).
2.	The network install path, if the system was installed using network install.
3.	The Windows CD-ROM, if the system was installed from CD-ROM.

If WFP finds the file in the cache folder or if the installation source is automatically located, WFP silently replaces the file. If WFP cannot automatically find the file in any of these locations, you receive one of the following messages, where file_name is the name of the file that was replaced and product is the Windows product you are using:

•	Windows File Protection Files that are required for Windows to run properly have been replaced by unrecognized versions. To maintain system stability, Windows must restore the original versions of these files. Insert your `product` CD-ROM now.
•	Windows File Protection Files that are required for Windows to run properly have been replaced by unrecognized versions. To maintain system stability, Windows must restore the original versions of these files. The network location from which these files should be copied, \\`server`\`share`, is not available. Contact your system administrator or insert `product` CD-ROM now.

The only way to delete, rename, copy or move is booting time when widows doen't use these file the same phenomena is used in anti virus programs when they clean an injected code from a system file requires you to restart your PC to take effect.

Windows also provides the ability to perform actions when it boots - before any programs are running. How this is specified is fairly obscure, and not something you want to deal with directly (it's buried in the registry, if you're really curious). Fortunately, there's a free utility to do it for you.

[Only registered and activated users can see links. ] is a free download that allows you to rename, copy or delete a file the next time you reboot your machine.
When run, MoveOnBoot asks you to specify a file:

In this case I've selected the file c:\t\pagra.txt.
Hit next, and you'll get a choice:

"Do not delete any [Only registered and activated users can see links. ] files or your system may become unbootable ..."
It's called MoveOnBoot because the most common, and perhaps safest action is not to delete the file, but rather rename it or move it to a different folder so that the program that eventually tries to load it won't find it. However, you can also instead make a copy of the file, or truly delete the file, if you so choose.
In my case, I'll select "Move", and then it asks:

I've left the location the same (c:\t), but simply changed the name of the file.
Finally, MoveOnBoot confirms what it's about to do:

Even though it says "Start", it simply schedules the action to occur the next time you reboot.
Now, when you reboot your machine, once it comes [Only registered and activated users can see links. ], the file specified will be renamed, (or deleted or copied, depending on what you specified) before any other program has an opportunity to place it "in use".
CAUTION: you can really hurt your system using this utility. Do not delete any Windows system files or your system may become unbootable and you'll need to [Only registered and activated users can see links. ] from your installation media.
Use this utility with care.
U can also download killbox.exe, NTFS4DOS and lot more.
