My laptop had another version of Windows on I think when bought it, but I upgraded it to Windows 10 Home. If I wanted to sell it on and factory reset, would it go back to the older windows, or would it keep windows 10? Cheers.
If you do a factory reset, it should revert back to it's original OS, assuming you have kept recovery partition/disks. However, should still be able to upgrade back to Win 10 OK after that
