Fresh speculation concerning Windows 10 has popped up which suggests that Microsoft is planning on introducing a switch that will allow users to easily turn S mode on or off.

So, a quick bit of background which might be useful: Windows 10 S was originally a fresh spin on the desktop OS that was designed to be more secure and locked down to run only apps from Windows 10’s store, and Microsoft later turned this into a simple mode, rather than a standalone variant of the OS.
