https://www.bleepingcomputer.com/news/microsoft/linkedin-job-post-confirms-windows-core-os-is-all-about-devices/ > Windows is an old operating system and several core components of the operating system make it impossible for the platform to adapt to newer devices. Microsoft is aware of these issues and the software maker is working on a new and modular version of Windows 10 which would be far more flexible and lightweight.  > This new operating system is allegedly called Windows Core OS - a modular version of Windows 10 streamlined for performance and security. The Windows Core OS is supposed to power the long rumored Surface Andromeda (dual-screen device) and the Surface Hub 2. According to reports, the company will not bring WCOS (Windows Core OS) directly to laptops, 2-in-1s, or desktops. Instead, it will arrive with the dual-screen Andromeda and the Surface Hub 2.
