@davathar: If you try to slipstream sp3 on a Vista or 7 machine it'll sometimes make the keys invalid... you have to slipstream it on an XP machine and it'll work... it happened to me lately... I have an original XP Home OEM CD with sp1 and I slipstreamed sp3 on it using my win7 os... when I went to enter the key from the sticker it said the key was wrong... I googled the problem and found this thread: http://social.technet.microsoft.com/forums...f-8df8050cff12/ which suggest slipstreaming on XP which I did and now the key works...
