Hey everyone. Ive got Vista Ultimate and a few things don't work. Like when you go to START/COMPUTER/PROPERTIES none of the buttons in the top left work like task manager an them. Its like that on a good few windows i open. Can't think of anything to fix them. Thats jus one of the many problems. Anyway if I was to start fresh with XP again would it take full advantage of my quad core and all that? Intel Core Quad CPU Q6600 2.40 GHz Let me no if any of ye know anything on it. Thanks!!
