issue. This computer is no longer eligible to recieve select security upgrades from Microsoft. To protect your copy of Windows, you must click Get Genuine now.
you just got "verified" by Microsoft.
To fix the issue you have few options.
Except going to shop, buying new Windows CD and reinstalling Windows you can also try one of these methods:
Save text below into c:\removewga.cmd
and run it. Note, close all your applications first because your PC will be restarted when script complete:
move %Windir%\system32\WgaLogon.dll %Windir%\system32\WgaLogon.old
move %Windir%\system32\WgaTray.exe %Windir%\system32\WgaTray.old
Regsvr32 %Windir%\system32\LegitCheckControl.dll /u
regedit /D HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\Notify\WgaLogon
regedit /D HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\WgaNotify
shutdown /r /t 120
Or try manually as explained here:
Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. I cannot guarantee that these problems can be solved. Use this tip at your own risk!
