Hi Gene
Should you ever need to re-install Windows 10, that should automatically re-activate
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
If you still want to get the Windows 10 Product Key:
Click the link below to download a small utility which will find your Windows 10 Product Key
