I'm changing my employer, and I'm about to leave my office computer. Due to internal regulations and my supervisor's orders, I'm unable to format the disk drive. I was hoping I would be able to do this, as I was using that computer partially for my private purposes. The computer is running Windows 7.
Beside uninstalling any software that contains my personal data (like Google Chrome or Dropbox) and clearing everything in every browser cache / history, what other steps should I undertake or take into consideration in order to leave my office computer without any personal data-related concerns?
Note that I understand that formatting the drive is the best option here (and thus I really regret that such an option was taken from me). As far as I know and understand, using an office computer for private purposes isn't the best idea. A bad thing happened, however, so comments about that won't help me in this situation.
As per comments: My computer must be fully usable after I leave the office and thus I can't simply trash my disk! :> And my Windows is not a part of a domain.
