bootcamp windows update usb not recongnized

I recently bootcamped my mac mini 2011 with windows 7. It's been working great for 4 months. last week it did a massive windows update (not my choice) and now my drivers are messed up. When I plug my usb monitor (non powered) in it thinks its connected via VGA. When I plug and extend the desktop with my HMDI it thinks my usb is connected via VGA and my HDMI is generic pnp. I reinstalled with bootcamp drivers, updated the network drivers.. I've tried everything i can think of. Help please! I have to use this tomorrow night for work.
