Presuming you want to sell it with windows running, first make a Window boot disk so you can recover. Then use DBAN (https://dban.org/) to completely wipe the drive. Then reinstall Windows up to the setup stage. The new owner will experience it as a new computer. Source: 11 months ago

You have a few options. The easiest in my opinion is just to smash the hard drives (assuming you don't want to reuse or sell them).
