Recent windows update has completely messed up my PC.

Hi all, This morning my computer was running perfectly fine, and then a windows update automatically installed itself and now my whole computer is messed up. I have no sound, two of my games won't work, I can't play spotify, local files or video files. I have tried literally everything. I have reset the drivers, uninstalled them, uninstalled the update, restarted pc a billion times, you get the point. It won't work with headphones or without, please help me. I need this fixed ASAP!!!
