Windows 10: Windows activation error 0xc004c003

Upgraded from windows 10 home to windows 10 pro. Windows 10 home was preinstalled when purchased.

Activation screen is listing windows 10 enterprise, which I have never heard of.

I paid my money for the upgrade and got nothing but trouble.

This process should be a lot easier in this day and age.
