Microsoft added some fixes in SP1 to stop people from using a bios hack to activate vista oem, but it seems to screw up some legit copies to.... So far it seems to only happen to a few, but its still irritating none the less...
After using vista for 6 months I'm going to reload up Xp Pro, Vista is a resource hog and it still has glitches even after SP1... From what I heard Microsoft is trying to rush out the next operating system to replace Vista because Vista been more or less a failure... 2nd to Windows ME as the worse operating system Microsoft has put out...
