Windows 10 - Reactivate after Repairs?

[Confused Guy]

Hello, everyone. I've recently got my PC back form repair and Windows is not activated anymore. Troubleshooting doesn't help at all. What should I do now?

Call the repair place, as a start?

do you have to use windows? if not a must, I suggest switching to Linux.

Assuming you have tried logging in to the computer with your Microsoft account, I would take it back to the repair place as JGL said. Just got back daughter's laptop having been sent to official HP repair centre. It came back with a similar problem, so it went straight back. Now working fine.

Did you try activating it? Was it an oem version of windows that came with pc when tou bought it? Or do tou have a windows installation key?

if you don't plan to use the notebook anymore, switch to Linux.

What did they repair? Switch the SSD? You can buy a new key on eBay for a few $. I always d/l Windows from MS and buy my keys on eBay.
