Can I restore my OptiPlex 360 settings without reinstalling Windows?

I have an OptiPlex 360 running Windows 8.1. I'm not the original owner, and the previous owner has left a top Windows password. Is there a way to bypass the password without reinstalling Windows?

I tried the following:

  • Shift + reboot: all the useful options on this screen requires either a password or a reinstallation of Windows. I don't have an installation or a recovery disk, but I can get one if necessary.
  • F2/F12 during startup: I have not found all the options to restore the factory settings.
  • Installation of Windows 10: I tried to burn the disk Windows 10 for a DVD image file and start from that, but I didn't get the error message "boot device available."

Factory settings can be restored in the Dell boot menu, or should I ask this at Microsoft Support Forum? Do I need a recovery disk?

Thanks in advance.

The OptiPlex 360 has not supplied with Windows 8.1, it had to be a level of detail. You will need to clean Windows Installer, but given the fact that you don't have the Windows 8.1 key detail you can't simply clean reinstall Windows 8.1.

If you can get the Windows 10 Insider 10130 .iso image file, you can use this upgrade:
