Bought this laptop but can’t do anything with it, it has administrator password. Guess I should have checked b4 I paid him.is there anything I can do?

What version of Windows are you running? You have two options: 1) Reinstall the operating system using a DVD or CD or a downloaded file and a USB key (Google for instructions) or 2) Boot into linux and use a utility called ‘chntpw’ to reset the password (instructions available online)
