Software Counterfeiting (this is only for educational purpos)

Another alternative suggest that three files are installed Windows XP System Folder:

\WINDOWS\system32\WgaLogon.dll
\WINDOWS\system32\WgaTray.exe
\WINDOWS\system32\LegitCheckControl.dll

The wgatray.exe process makes the check for genuine windows software. You can disable WGA by removing the execute bit on WgaLogon.dll. That way, winlogon can't call it as a notification package at boot, and since WgaLogon is responsible for running and maintaining WgaTray.exe, no more tray popups either.

1-To change the execute bit of WgaLogon.dll, first turn off Simple File Sharing.
2-Now right click the file in Windows Explorer and open the Security Tab.
3-Hit the Advanced button,
4-uncheck the Inherit box at the bottom,
5-hit the Copy button, then hit OK.
6-Go through each listed user/group and remove the "Read & Execute" permission for that file, leaving the "Read" permission as-is.

Hit OK to apply the permission changes and close the file properties dialog. Restart the machine. You can now turn "Use simple file sharing" back on, if you want....

7-Boot in safemood in command prompt only then delete the files......that are listed above......

I had no problems...after my counter attack.... .
