That crashing noise

You’ve started one of your computers after returning after a week away from the office, and you find that your PC crashes with a Windows Stop Error shortly after login. You then discover that a series of patches and OS updates were made while you were vacationing. Which of these options would be the best choice to begin the process of returning your system to a workable state?

A) Restore the computer with your last monthly system image backup

B) Reinstall the operating system from the original installation media

C) Use System Restore and choose a prior restore point

D) Restore the \Windows directory using your last Windows Backup

E) Head back to the beach for another week and try not to think about it
