Remove the awful Windows XP WGA screen in one minute

Of course, I do not use windows at all, but a friend of me asked me to help him to remove the WGA (Windows Genuine Advantage) screen :-)

I typed these bunch of commands and the problem was fixed.

c:
cd windows\system32
ren WgaLogon.exe WgaLogon.exe_
ren WgaTray.exe WgaTray.exe_
Regsvr32 %Windir%\system32\LegitCheckControl.dll /u
shutdown -r -t 0
