How do I delete my internet searches besides history, cookies, and temp files?
I have to turn in my company’s computer to get another one. When I stay in motels I play on the computer off of the hotel’s wireless service, but we are only supposed to use it for business purposes. Is there a way to delete my searches for games, news, etc. so they don’t know?
