According to reports, Microsoft is working on the next generation of its Windows operating system (OS) with a focus on web and security. Windows Central reported on the ongoing development of the “Windows Core PC” project, which is a successor to Windows Core OS, which was discontinued in 2021. The Windows Core OS project was designed to make the OS more lightweight, enable faster updates, and feature modular UWP to support new form factors such as foldable displays and folding screen laptops, which were said to be the target for the Windows 10X release that was ultimately canceled in favor of Windows 11.
The current Windows Core PC project differs from the previous one as it includes compatibility with existing desktop app environments, including Win32 apps. It has been developed as a modular platform that can be adapted flexibly for different hardware configurations, enabling it to be used across a range of form factors. The key difference between this and the current Windows 11 is that the new system separates the “state” of the OS, introducing a read-only partition that users and third-party apps cannot access, similar to Android OS. This allows for faster updates and a more secure platform. In contrast, Windows 11 installs on a single partition that can be written to, containing system files, user data, and program files. The Windows Core PC will split the OS across multiple partitions, making it possible to reset the system more easily, as with Chromebooks.
While Windows Core OS was a project to rebuild the Windows platform from scratch, Windows Core PC is designed to dismantle and reassemble the existing Windows platform as modular components, making it possible to maintain support for legacy apps and environments. The new version of Windows is reportedly designed for educational use and will run only the Office suite. Early internal testing suggests it will be between 60% to 75% smaller in size than Windows 11 SE.
Microsoft is also developing silicon optimized for the Windows Core PC, similar to Apple’s M1 chips. The new silicon will focus on AI capabilities and be designed to optimize the vertical integration of hardware and software. Some AI features that are currently under development include the ability to analyze display content, provide contextual prompts for launching projects or apps based on the information being viewed, and identify objects and text within images.
