Windows Genuine Advantage (WGA) is an anti-piracy system created by Microsoft that enforces online validation of the licensing of several recent Microsoft Windows operating systems when accessing several services, such as Windows Update, and downloading Windows components from the Microsoft Download Center.
WGA consists of two components: an installable component called WGA Notifications that hooks into Winlogon and validates the Windows license upon each logon and an ActiveX control that checks the validity of the Windows license when downloading certain updates from the Microsoft Download Center or Windows Update. WGA Notifications covers Windows XP, Windows Vista and current versions of Windows 7.
If you get this logo upon your Windows logon, which mean Microsoft had detect you are using pirate windows. Don't be panic, there come the solution. It work for XP, Vista and even Windows 7!
