Graphics drivers were moved into user mode in Windows Vista. If you've ever seen the screen blink, and a balloon pop up saying that the graphics driver was restarted -- that would've been a bluescreen in XP. I wonder why they didn't move the rest of GDI out of the kernel at the same time? A composing window manager was also introduced in Windows Vista, which really cuts down on the number of window repaints. Surely they can afford to take the performance hit now?
