To control piracy, Microsoft started WGA (Windows Genuine Advantage) system to control it’s duplication long time back. At first it tested with Windows XP and later it got applied on Windows XP systems also. But finally it’s bringing a change to it’s piracy control system by replacing WGA with WAT (Windows 7 Activation Technologies). Windows 7 Activation Technologies is more powerful and convenient way to activate your copy of Windows 7. While Windows Genuine Advantage will be there for XP systems, WAT will replace it on Vista and Windows 7 copies.
IF you still haven't update your window 7 with Download WAT Update (KB971033) you can mark this update for exclusion.
If you have update with KB971033, you can use this software to remove the WAT notification.
