PSA: Be careful in Device Manager.

I was cleaning up old drivers in Device Manager and accidentally uninstalled (and deleted) my audio driver. Now I have no sound, and there's a yellow exclamation mark next to "Multimedia Audio Controller" or nothing shows up at all.

PC is now sitting there silently mocking me. No sound, no music, no YouTube. Anyone know a quick fix besides reinstalling Windows? #TechFail #PCProblems
