Kim got a computer recently from a friend and she can't log into her account. It keeps asking for the previous owner. Leo says that the best thing to do is format the hard drive and start over. That way she can set it up for her preferences and make her account the primary account. Windows 10 has great reset options, and she won't even need a Windows key anymore. She should just make sure to back up her data and files first. Then hit the Windows Key and type "recovery." She'll get the choice of several options. Then she can run the recovery and it'll reinstall Windows. She'll have to reinstall all of her programs after that. She should make sure to run updates too.
