I know this is a mac forum so I'm posting here in hopes that somebody can help. I have an older spare PC that needs to be sold. It's running windows 7 pro and I don't have any associate disks or otherwise. It's in fine shape and runs well. I've copied all important data off and now I want to prepare it for sale. It's had it's fair share of personal information on it so it need some form of cleanse but with out a disk to reinstall the OS I'm afraid up ****'s creek. I really don't care if I sell it with/without a working OS but it would be nice to prove that it works and runs fine. Any tips that my mac focused mind can handle. I've gone to google and besides a bunch of scamming looking software nothing really jumped out at me. Thanks in advance for your help!
