I got this from this site from Microsoft to "Vinman":
Head to C\ Documents & Settings\ All users\ Application Data\ Windows Genuine Advantage(folder). And delete that folder. I did & I don"t have any more "validation" messages. Windows Update did keep trying to download the accompaning update # ??? that came w/ it, but I played w/ the Auto-update in Control Panel/ Windows Security. If this helps anyone, great!
