This is a known bug in the Home to Pro upgrade process, where the Enterprise edition gets installed instead of Pro, use this fix with the generic Pro product key:

Important - disconnect totally from the Internet

Open the Settings App (Gear icon on your Starr Menu)

Go to Update and Security - Activation

Click Change Product key

Enter this generic product key: VK7JG-NPHTM-C97JM-9MPGT-3V66T

When prompted, click 'Activate Product'

If the above does not work first time, restart your PC and try again.

Note the generic key will cause Enterprise to downgrade to the Pro edition, then your own legal licence will activate automatically after you restart (not shut down) your PC
