MSKB: Windows Genuine Advantage Notifications application

Windows Genuine Advantage Notifications notifies you if a copy of Microsoft Windows XP is not genuine. The notification messages only appear on computers that have failed the Windows Genuine Advantage validation process and that are running a copy of Windows XP that is not genuine.

If you are running a validated, genuine copy of Windows XP, you will not receive notification messages. Description of the Windows Genuine Advantage Notifications application
