Dear friends,
Please do the following procedure which I did and got rid of the Windows Genuine Advantage headache successfully. I got it from google search.
Lauch Windows Task Manager.
End wgatray.exe process in Task Manager.
Restart Windows XP in Safe Mode.
Delete WgaTray.exe from c:\Windows\System32.
Delete WgaTray.exe from c:\Windows\System32\dllcache.
Lauch RegEdit.
Browse to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows NT\CurrentVersion\Winlogon\Notify
Delete the folder WgaLogon and all its contents
Reboot Windows XP.
Note: With this method, you may be prompted to install WGA Notifications again which can still be unselected.
hope and wish you too get rid of the headache....
regards.
