I did Windows Update on my computer which is a Windows 7 Pro, it finished updating and Aero didn't work anymore and said my GPU couldn't run Aero, so I thought updating my GPU drivers would fix it, I rebooted and I was greeted by a BSOD saying " c0000135 The program can't start because %hs is missing from your computer " which keeps me from getting into Windows. I'm currently dual-booted into Ubuntu on the same computer, what can I do to fix Windows?
