Device Manager Crashes - Microsoft Management Console Error

I can open device manager, but whenever I try any function, search for new hardware, update drivers, disable device, etc, device manager crashes with the error "Microsoft Management Console Has Stopped Working." Other Management console programs work fine (event viewer, performance monitor).

I've run sfc /scannow half a dozen times. I've run it from a clean boot, I've run it 3 times in a row, I've run it, restarted, and then run it again. No errors found.
