If we consult years of insider whispers about Microsoft’s alleged internal strategy for Windows, many from The Verge’s own Tom Warren, there’s a simple reason why you shouldn’t care whether Windows 10X ships on just a few devices or thousands. That’s because Windows 10X is likely just a modular shell that gives the core Windows operating system a new user interface to do the tricks you see in these videos.
And it all comes back to the philosophical question of what “Windows” really is now.[…]
As Tom and fellow reporters have discovered, Microsoft has been building a new Windows Core OS (WCOS) that will serve as the new modular backbone of Windows. It can be paired with a different user interface for different types of displays by adapting what Microsoft’s calling a Composable Shell, or CShell (say it out loud), to each new interface.
I hope Microsoft will eventually give users the choice to switch between the various shells whenever they so desire. And if not – the community will take care of it.
