Windows 10: Windows won't reactivate after changing motherboard and cpu

I just upgraded my PC, and windows deactivated itself. My windows key is linked to my microsoft account, and the original product key is probably long gone (it was a Windows 7 key from 5 years ago). I tried using the activation troubleshoot in settings. When I click "I changed hardware on this device recently" it shows me my PC with a checkbox saying "This is the device I'm using right now". I checked it and clicked activate and it just says "Unable to activate Windows We can’t reactivate Windows on this device. Try again later." I also checked my microsoft account devices page and there are two copies of my PC there now, one with my old specs and one with the new. How can I reactivate windows?

win 10 motherboard change, reactivating windows

Hi Famie,

If you are planning to change your motherboard, you will still be able to activate your Windows 10. In Windows 10 version 1607, there is a feature that you can link your Microsoft account to Windows 10 digital license on your device.
This can help you reactivate Windows using the Activation troubleshooter if you make a significant hardware change later, such as replacing the motherboard.

That being said, we suggest that you follow the steps given on this article
to reactivate your Windows 10 after a hardware change.
