Yeah, XP did that with most of the drivers other than graphics, which lead to a reduction in BSOD crashes (because if a user thread crashes, the OS just kills it and continues on, but an unhandled kernel error will crash the entire OS to a generic “turn the screen blue, report and error, and log it, if possible”).
Vista further improved this by moving most of the graphics driver code out of kernel land.
The actual technological advancement of Vista was userspace graphics drivers.

Also correct.
