OEM keys are saved on the EPROM that will be lost when you replace your MOBO and will require purchasing a new Windows license. When you run: wmic path softwarelicensingservice get OA3xOriginalProductKey command in the Command Prompt opened as administrator you will get a 25-digit key that you may use to download an ISO file, etc., but this is a "public key" not the actual registration/activation key. With Digital License, there is no need to know your product key or purchase another product key if you lose it. Anytime you need to reinstall Windows 10 on the same computer, just proceed to do so using any of the available options. Windows 10 will automatically reactivate without asking questions. https://support.microsoft.com/en-us/windows/get-help-with-windows-activation-errors-09d8fb64-6768-4815-0c30-159fa7d89d85#ID0ELD=Windows_10
