how to reset windows?

[jane1]

I decided to sell my computer so I wanted to refresh my computer so that, any other user cannot access my personal documents. I learned the process from https://errorcode0x.com/refresh-reset-restore-windows-to-factory-settings/. But I couldn't understand how to refresh windows 7. Can anyone help me?

Which computer (brand / type) do you use? A factory reset may be possible.
