While news leaked of the plans last month, Microsoft VP Joe Belfiore confirmed them on Twitter today. “Next year 10S will be a ‘mode’ of existing versions, not a distinct version,” says Belfiore. >The new S Mode will lock down any copy of Windows 10 so it can only run apps from the Microsoft Store, and will work the same way as the dedicated Windows 10 S operating system was built to do. Microsoft is planning a new “S Mode” for Windows 10 Home, Enterprise, and Pro versions of the operating system.
