Windows Reactivation
In Windows settings, navigate to the activation area and select troubleshoot. It will scan for issues, confirm no problems exist, then display a link stating "I recently changed hardware on this device." Clicking it will turn off your previous motherboard and turn on the new one. Remember, your Windows activation code must be connected to your Microsoft account for this process to work.
It does not indicate that the statement is limited to linking your account.
You must connect your account. Is there anything stopping you from doing that already?
Was the old computer factory-made or built in-house? Did you purchase it with an OEM license? All those details are written on the old motherboard, meaning you’ll have to buy a new license.
