I just bought a used Dell desktop for my 96-year-old father from Marketplace. He tends to wreck every computer I give him with viruses, so I'm done buying him new ones. This Dell requires a 4-digit pin to log in under the previous owner's name, who didn't reset the computer and hasn't answered my request for the pin. I'm more comfortable with Apple products, so I need help figuring out how to create a new user or get into the system. Any suggestions?

The easiest way might be to just reinstall Windows. You can create a bootable USB drive using the Media Creation Tool from Microsoft. Just find a working Windows machine, download the tool, and follow the steps to create the USB. Boot your dad's computer from it, and you'll be able to install a fresh version of Windows. Just remember to set his account as a limited user to keep viruses at bay!
Have you thought about giving him a limited user account? That might help reduce the risk of malware. You could also use antivirus software that requires a password for extra protection. Just a thought!
If you're struggling with Windows, maybe consider installing something like ChromeOS or Linux. My dad, who's 75, was hesitant about Linux at first but now loves it and won’t switch back to Windows.
Honestly, it sounds like you should format the computer and reinstall Windows from scratch. Check out this link for the Windows 11 installation media: https://www.microsoft.com/en-us/software-download/windows11. Just make sure to set up Windows Defender and don't make your dad an administrator. This way, he’ll be less prone to viruses.
