Windows 10S is, in the simplest terms, Microsoft’s Chrome OS competitor. A spiritual successor to RT, the operating system is a slimmed down version of Windows 10 with added security (by way of locked down app installs) and lower hardware requirements designed to be run on sub-$300 systems that can be purchased in bulk by schools.

The messaging on the software was always a bit messy, though, and the company didn’t really do itself any favors by launching it on the high-end Surface Laptop. This morning, however, VP Joe Belfiore confirmed via Twitter the company’s plans to streamline the offering, essentially reinventing 10S as a “S Mode,” a option baked into the larger Windows 10 operating system.
