Windows 10: used PC blocked with passwords

I bought a used HP PC at a flea market. The seller showed me that it worked OK. I used it and it did work OK. But after I brought it home and tried to set it up the way I wanted it I found that I couldn't do anything without entering a password. I tried to install ccleaner, bit defender, malwarebytes but had to enter a password to do it. Can't open system restore without a password. Can't open computer management, user accounts in control panel, or change any settings at all. I can't uninstall some of the things I don't want either without a password. Everything I try to do I have to enter a password. I don't know who the seller was to get the password from him. It boots OK and then asks for a password. I press enter and it then continues to desktop. The computer works fine otherwise. How can I turn off this asking for a password for EVERYTHING I do? In a way I feel like I'm locked out of my computer. Thank you.

New FF - passwords


Hi:

If that setting is already enabled, then I suggest as the next troubleshooting step might be Mozilla Safe Mode (not to be confused with Windows Safe Mode)):
