Hi Aiden99-
I'm Kevin B. Windows user like you. Thank you for sharing your concern, let me help you sort things out
Activation depends on what type of license you have:
If it came preinstalled with the computer, that is called an OEM version. For an OEM license, the license remove as soon as Motherboard is not working. So basically,it is non-transferable. If that is the case you need to get a new license.
If its the free upgrade from a retail store, it is transferable to a new computer or motherboard.
If its the free upgrade from a OEM preinstalled Windows license, it is NOT transferable to a new computer or motherboard.
However, this is not same for retail licenses.
Example: You purchased the license through Microsoft store. That does carry transfer rights.
To activate your Windows:
Run the activation troubleshooter on the new device using the below steps:
Go to Settings>Update and security>Activation and run the troubleshooter. and select I recently changed hardware on this device.
