Windows 10 activation issue

Occasional Visitor

So I took my laptop for repairs and they wiped it, doing a factory reset. Unfortunately they didn't really know what they were doing as they couldn't get my Windows 10 back. So they've put an unactivated version of Windows 7 on it. I bought this laptop for campus in 2016 and it came with windows 8, and a free upgrade to windows 10 (which I used and was running win 10 smoothly). How do I get back to windows 10?

it sounds like your activation and product key was tied to your Microsoft account, so chances are if you install Windows 10
and sign in with your Microsoft account, it will be automatically activated.
but if it doesn't, please refer to this page:
