I was given an hp touchscreen laptop from a friend that ownes a towing company and it was in an impounded car that the bill was never paid for so now our friend ownes the car. The laptop so far seems to be running properly but I am unable to do anything since whoever owned it obviously signed in with a password and this person also was the administrator. I am able to get in under guest but I can't make a new profile for myself and I can't delete there's and I can't change settings on the computer since I'm under guest and everything asks for this persons password. How do I delete the past user since they were password protected and how do I make a new profile and become the administrator??
