Windows reactivation after replacing my motherboard not working

Hi there!

Yesterday I swapped out my motherboard because my old motherboard would no longer boot up. Unfortunately, now I'm running into an issue where Windows is not being activated automatically. I did a clean reinstall of Windows 11 home edition on the PC.

I'm logged in with the same Microsoft account and I've tried using the troubleshooter, pressed the button 'I recently changed hardware on this device', but it's stating that there are no devices found to use the product key from. This is strange, because it's the same computer as I was using before (just with the new motherboard). Unfortunately I couldn't find any way to speak to someone from Microsoft directly, so that's why I'm posting the question on here.

It would be a shame if I had to buy the license again.

Kind regards,
Rick

A new motherboard is considered the same as a new PC by the activation servers.

Where did you get your Windows licence was that pre-installed on the PC or did you purchase a full retail Windows licence from Microsoft or from a 3rd party retailer?

Or is your Windows licence based on a previous Windows 7 or 8 licence?
