I would like to sell or donate an old laptop, a Toshiba Satellite T235D-S1345, 64 bit, Windows 7. I know I need to wipe the hard drive but would like to keep the preinstalled games that came with the laptop for the next owner. Any way to do this? If so, can you walk me through the steps to get rid of any personal information? I have already uninstalled programs and deleted personal files, but I know there are more steps I need to take to completely eliminate the chance of any of my personal data being recovered by anyone. Thank you!
