I hate to tell you all but all of Microsoft products since 3.1 have had more security faults and privacy violations than one can count in a lifetime. But to defend XP users, VISTA is a system hog and it has 100X more security faults and privacy violations (Oh oops you agreed to the EUA didnt you? Well you signed away your rights to privacy there) than Windows XP. Microsoft is clinging to the Gamer World, barely. Thats what VISTA was really about. Do you honestly think that they will give people who have XP the same ability to play games with smooth candy graphics when thats all they have to market a UNSAT piece of software. Be serious Microsoft is as bad as SONY for caring about the actual customer...

NO DX10 will not be available for XP users... Be serious.
