The structure for graphics drivers changed completely from Windows XP To Vista. So forget your video card. You might have the latest and greatest money pit of a video card, but it still won’t run Battlefield 3.

Microsoft built 7 from the ground up to be a secure computing environment and retained the key security features that helped protect Vista, such as Kernel Patch Protection, Data Execution Prevention, Address Space Layout Randomization, and Mandatory Integrity Levels, but Windows Vista and Windows XP are equally at risk to viruses and exploits and overall Vista brings only marginal security advantages over XP. Net gain, zero.
