I installed Windows 7 , 2 days ago and i am trying to remove WGA. I have removed all the annoying messages with RemoveWAT 2.5 but i still can't change my desktop wallpaper.
You have an outdated version of Windows (Build 7077, a beta or something leaked) the most recent version is 7601 (Windows 7 Service Pack 1), you should obtain the most recent version from here forums.mydigitallife.net/threads/28517-Windows-7-w-o-SP1-and-SP1-Media-Refresh-Direct-Download-Links, and forget about RemoveWAT, it's outdated and works like s**t messing up system files, try Windows Loader by Daz in this thread forums.mydigitallife.net/threads/24901-Windows-Loader-Current-release-information
