I have a Dell Inspiron 1525 laptop that is a couple of years old, originally bought at Best Buy. I decided to upgrade to a newer laptop several months ago, and have found someone willing to purchase my old laptop. I have moved/ backed up all the documents/ pictures/ music from the old Dell Inspiron. I want to delete everything that I added, but not restore to factory settings as it will uninstall the windows programs (word, excel etc) that I bought with the laptop originally.
Any tips to making sure I am not leaving any personal information on the hard drive when I sell it to a complete stranger. Thanks!
