Activation errors after motherboard replacement

Starting with Windows 8 and continuing with Windows 8.1 and Windows 10, most PC manufactures are injecting their Windows product key into the motherboard of the PC.
This allows the PC to activate automatically when you first boot up the PC and to re-activate if the PC is ever reset or needs a clean install.
The product key in the motherboard is edition-specific and will only activate that edition of Windows (Home, Pro, etc.).

When the motherboard is replaced under warranty, Windows will detect a hardware change and look for the new product key that was included in the replaced motherboard.
Sometimes the new product key is not retrieved by Windows, and you get
Activation Error 0x803F7001. The troubleshooter will ask Windows to re- try retrieving the product key from the new motherboard and activated it.

Correcting the mistake of entering a Global Volume License key

The troubleshooter also corrects a second, less common issue.
If you searched the web, you might have found and entered a Global Volume License (GVL) Key.
GVL Keys only work for PCs in an Enterprise environment where the administrator has setup this system of licensing.
If you mistakenly entered a GVL Key, you PC will no longer accept regular product keys, and will give the activation error 0x8007007B (or even 0xC004E016, 0x8007232B, 0xC004F074, 0xC004F038).
This troubleshooter will identify the GVL Key and replace it with a regular retail default key.
Your PC will not activate yet, but now will accept normal retail and OEM product keys.
