True. That's why I regularly delete all the temp files and cleanse the Registry, and also why I never save anything like a credit card number that I wouldn't want to get loose. Other than that, I don't really have anything on my computers that I wouldn't want people to see.
If I had some sort of criminal records it would be different. But other than taking precautions to avoid identity theft, I don't really worry about it.
I agree; if this lady is paranoid, or has real secrets, or doesn't know who the buyer is, then she should at least delete and reinstall the whole operating system. But even that isn't enough if you're talking about vital secrets and the possibility that a computer expert will get hold of the hard drive. If you are bill or hillary clinton, then you want to destroy the hard drive with a blow torch or a sledge hammer before you put the machine out in the garbage.
I agree. If she's that paranoid, she should just blow it up. Half a stick and an acre of property will do the job.
