Upgrading Windows 10 Home to Windows 10 Pro – Error Code 0x803fa067

We came across an unusual problem today when trying to upgrade a client’s computer from Windows 10 Home to Windows 10 Pro.

As per Microsoft’s instructions (https://answers.microsoft.com/en-us/windows/forum/windows_10-windows_install-winpc/how-to-troubleshoot-product-activation-in-windows/33f31475-93b3-4d1c-812f-4b21fbd807a7?auth=1), we were first entering the default Windows 10 Pro key: VK7JG-NPHTM-C97JM-9MPGT-3V66T to convert the version of Windows 10 Home to Windows 10 Pro but after clicking “Start” we were presented with an error box “Unable to upgrade your edition (0x803fa067)”.

After numerous calls to Microsoft who couldn’t resolve the issue, we tried unplugging the network cable before clicking “Start”. This resolved the issue! Windows then upgraded itself to the Professional version after a reboot. Then we were able to activate the PC with a valid Windows 10 Pro license key.

Hope this helps someone out there!
