Microsoft is secretly developing Windows Core OS and is expected to replace the existing Windows 10 operating system in the future. Although Microsoft has yet to officially announce the project, Windows Core OS has been mentioned several times in official support documents and LinkedIn recruitment messages. Microsoft is developing Windows Core OS for Windows 10, Xbox and Windows Reality, according to LinkedIn personal work history released by Microsoft engineers. And based on job introductions, future versions of Windows 10, HoloLens and Xbox will be based on Windows Core OS.
“Our team is creating Windows Core OS: it will be the foundation for the future Windows 10, Windows Mixed Reality, and Xbox operating systems,” the Microsoft Engineer Recruitment Request reads. The team’s current focus is on Windows 10X, a system developed for dual-screen devices such as Surface Neo, which are expected to go on sale over the 2020 Christmas holiday season. “
More interestingly, Windows Core OS will become an operating system for future Xbox releases in the recruitment message. This means that the previously rumored “GameCore” feature allows game developers to “create once, run anywhere” effect. That is, developers only need to create one time to run on multiple platforms.
