I recovered my old laptop that I gave my daughter when she went to college. The only thing I could find was the laptop, however, I do have the original software for the operating system and applications. I purchased a power adapter, plugged it in and found that there is an admin user that I did not create when I first set up the computer. She has no idea who did it, why they did it, nor the passcode to get into it. Therefore, even though I have my admin user account that I set up, I cannot delete this user account due to lack of privilege. So, is there any way to delete this account without having to reinstall everything?
