A driver is kernel-mode code that's written in C. It can do just about anything, and when there's a bug, you're in trouble. I'd like to see Microsoft allow more drivers to run in user-mode, but this is just the risk you take when installing drivers. Microsoft has been tightening driver signing requirements, so you can at least be sure they're from a known source.
