This sets everything back to default so that if there is a Digital License issued during a proper Upgrade it should reactivate.

#Microsoft windows license center license key
If you know the present version of Windows originally was legitimately activated then to fix the problem what I would do is go offline to remove the Volume License key and then restore the Generic Product Key that is used to activate with the Digital License issued by Upgrade or Factory install, the factory key embedded in the UEFI/BIOS firmware chip, or the retail key you used. Normally this would be caught during Upgrade and flagged then, so has anyone had the PC who might have done this? If not how about in Windows 10? It is also a way pirates illegally Upgrade to Pro version. Sometimes this is done by shops or others reinstalling Windows - unnecessarily because the PC either came with a Windows Product Key embedded in the BIOS/UEFI firmware, or it was already activated by free Upgrade or a retail Product Key, and would have reactivated after a reinstall had they given it the chance and not interrupted this by installing the illegal key. It's using a Volume License Key which can only legally be used by large organizations which activate fleets of PC's via an on-site server, where they must check in regularly or they expire. The Edition in the last screenshot tells us what's wrong.
