Why do I get the error "You're running non-genuine Windows 10 Home" when I try to switch out of S mode?
You will not be able to switch from Windows 10 Home in S Mode to Windows 10 Home until your copy of Windows is activated. If you try to switch before the activation is complete, you will receive the error shown below.
If you receive this message, you should connect your computer to the internet and activate Windows. After Windows has been activated, you can Switch out of S Mode.
