My computer may be a victim of software counterfeiting..the copy of windows did not pass genuine windows validation

There is actually a way to bypass the comment " your computer may be a victim of software counterfeiting..the copy of windows did not pass genuine windows validation".  
try this:
1.Kill the process wgatray.exe in Windows TaskManager (Select it then right click and select End task) and restart Windows XP in safe mode. Now delete the following files:

Delete WgaTray.exe from c:\windowss\system32
Delete WgaTray.exe from c:\windows\system32\dllcache

Start Windows Registry editor and delete the folder "WGALOGON" located in the following location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Windows NT\CurrentVersion\WinlogonNotify.
Delete all references in your registry to WgaTray.exe (repeat search using F3 function key).
