To all the people who were working feverishly towards important deadlines and thought to themselves, now would be the perfect time to make a modification to my operating system: give your head a shake. If you don't have a backup and/or can't afford to spend a measely couple hours restoring the backup or performing a reinstall.... why would you do this?
