Windows 10: Re-activation after motherboard change on a Win 10 with the free upgrade from win 7

I have recently upgraded my motherboard on a system which had genuine win 7 that got the free upgrade to win 10. Now it asks for activation but I don't have a valid win 10 key and on the troubleshooting page it says the ones that upgraded from Win 7 got the "digital license", but no mention on where to find it and weather I can use it instead of a product key.

Activating Win 10 after replacing Motherboard

I recently had to replace a motherboard on a Lenovo ThinkCentre due to a blown power supply. After recovering, Windows was not activated and I can't use the troubleshooter to remediate. This system was shipped with Win 7 Pro and upgraded to Win 10 during
the free promotion offer.

Does anyone have suggestions on how to get Win 10 reactivated in this scenario?

Also any thoughts on why Win 10 doesn't recognize the DVD or USB ports in File Explorer?

 

Changing Motherboard on Win 10 that was upgraded from Win 7 OEM

I am wondering what I need to do after replacing the motherboard on my PC to get an activated version of win 10 Home. I realize that due to OEM version on win 7 before upgrade that I now have an OEM version of Win 10. I was not planning a fresh install
so was hoping to boot up and install the necessary drivers for the new motherboard. If this works I assume I have to purchase a new license. Can I purchase a key online and just simply enter it to activate or will I need to fresh re-install. Moving from
Intel z68 to Intel z170 skylake. Thanks...

 

Activate Win 10 Pro after motherboard/OS upgrade

After parallel PC upgrades of motherboard and OS, (Win 7 to Win 10 Pro) I now need to activate Win 10 Pro. Can I purchase a digital license or product key to complete the task? I would prefer not to have to perform a clean install of Win 10 Pro as my system
is working fine as is. I just need to activate the Win 10 Pro that's already installed.
