The company is working on a compatibility layer codenamed Neon for legacy apps that require a shared state OS to function, too.ĬorePC installs into multiple partitions, not just one. Microsoft is also working on a version of CorePC that meet the current feature set and capabilities of Windows desktop, but with state separation enabled for those faster OS updates and improved security benefits. A version of Windows that only runs Edge, web apps, Android apps (via Project Latte) and Office apps, designed for low-end education PCs is already in early testing internally, and is roughly 60-75% smaller than Windows 11 SE. My sources tell me CorePC will allow Microsoft to finally deliver a version of Windows that truly competes with Chromebooks in OS footprint, performance, and capabilities. If Windows Core OS was an effort to “rebuild” Windows from the ground up as a modern, configurable OS without the overhead of legacy app compatibility, Windows CorePC starts with the full Windows desktop and works backwards to break it down into a modular, configurable system while maintaining native support for legacy apps and workflows where necessary. Microsoft is essentially tackling its Windows Core OS vision from the other end of the spectrum.
