Digital activation key

Hi Tony

You do not need a product key to re-install Windows 10, as long as you re-install the exact same Edition of Windows 10, your licence will be unaffected and Windows 10 should self-activate without any user interaction . . .

If you have already re-installed Windows 10 and you have an activation error, please check you have installed the same edition - go to Settings - System - About. Is the correct Edition of Windows 10 listed there that matches the previously installed Edition?

If you are about to re-install Windows 10:

Since you previously had Windows 10 installed and activated on that PC during the installation process skip the steps which ask for a product key and select the option 'I am Reinstalling Windows 10 on this PC', and activation will not be an issue, your PC will
have a digital entitlement stored on the Microsoft Activation Servers

 

Identifying PC's from Digital Activation in microsoft account

You will not need the product key to transfer a license. You have done it correctly by using a Microsoft account to register your digital licenses. it makes the transfer easy.

When you have replaced the motherboard and boot the PC in its deactivated state, check the computer name. It has remained unchanged, being the same it was before motherboard was replaced. When you know the PC name, select I recently changed hardware on this device:





Sign in with your MS account. You will get a list of your registered devices. Select the same PC from the list, click Activate and continue following on-screen instructions:

In my case, I have never had any issues to do this. Only information you will need is the name of the PC to transfer its license to new hardware setup.

 

Windows won't activate a digital license but will with a product key?

If you plan on "transferring" a digital license from one computer to another using the activation troubleshooter and your Microsoft Account, then yes, start with the generic product key on the new computer. Actually, on a new install, you select the option for "I don't have a product key" and then after the install use the Activation Troubleshooter. Otherwise, if you are using a unique product key, either purchased or embedded in the firmware of the computer by the factory - let Windows 10/11 activate for the first time from that product key. AFTER it is activated, change the product key to the generic. One advantage to doing this is that if the original product key was OEM, changing it to the generic retail product key will also change the digital license type to retail and make it transferrable to another computer.
