Windows 10 S

Windows 10 S is a featured-limited operating system released by Microsoft Corporation for low-end devices, based on Windows 10. Microsoft began phasing out this version of Windows 10 in favour of Windows 10 Home or Windows 10 Pro devices operating in "S Mode" by default (which only allows applications to be installed from the Microsoft Store); "S Mode" can be disabled on these Home and Pro devices free of charge.
