Take it to a local computer shop that does repair, etc. and have them wipe and install Win10....that what I did.
Not to discourage anyone but the last time I did that, I learned my local computer shop owner was far too interested in my personal information. He started exploring my photos before I even left the shop.
Moral of the story, make sure you can trust the local computer shop.
Aside: I hate Windows 10. Got a new laptop with every bell and whistle imaginable, and that infernal Windows 10. Next time I'll just overpay for a Mac.
