I know, i guess i can understand it checking once, but after it finds a legal xp install it should uninstall its self, leaveing some marker that it has validated the install. or maybe it should only run when automatic updates is installing updates. imho, it is a bad move by MS to have this program in the first place. makeing it even worse is that it contacts them daily...and on top of that they forgot to point out this "feature" ?
