I came across an upgrade issue when I was upgrading Windows 10 Home to Windows 10 Pro using the Change Product Key feature. I first entered the default Windows 10 key from Microsoft VK7JG-NPHTM-C97JM-9MPGT-3V66T to convert the Windows 10 Home to Windows 10 Pro and when I clicked the start button to start the upgrade, I get the error saying that the the installation does not have a valid digital license with the error code Unable to upgrade your edition (0x803fa067).
The solution is very simple
– Boot the computer
– Open the activation screen
– Change the Product Key to VK7JG-NPHTM-C97JM-9MPGT-3V66T
– Disable internet connectivity by disabling network card
– Click start for the upgrade
