No Microsoft upgrade to keep up with the hardware technology changes somewhat. XP is 32 bit almost exclusiviely. MS releases products based on the industry as a whole. MS doesn't make touch screens, graphics cards, Hard drives, Motherboards, printers or processors. They just make an OS that runs those things. Like someoneposted Intel has been making 64 bit processors for 10 year and AMD even longer. yet you want to stick will a 32 bit OS? The whole industry evolves with new technologies. Soon we will have 128 bit hardware.
