Insider sources at Microsoft have spoken of continued efforts to modernize the core of its operating system, with the work-in-progress Windows 12 cited as the ideal candidate for substantial updates. The engineering team is reported to be integrating a modular design, which will allow for a reduced operating system footprint - similar in principle to ChromeOS. According to a Windows Report article the operating system development team is hard at work on a spiritual successor to the abandoned Windows Core OS project. Their newest effort is reported to be called "Windows CorePC" and Microsoft is aiming to hit the same goals it set for its Windows 10X edition, which was cancelled in mid-2021, but they will also target native support for legacy applications on devices that require necessary access.

Windows Core OS was shutdown after years of development and internal testing - it was hoped that a modular Universal Windows Platform-first (UWP-F) operating system would be more lightweight and gain stronger security features, as well as greater access to regular updates. The inside sources stated that Windows Core OS will not be developed any further, at least not for desktop computer purposes. The Microsoft team is anticipating that its new CorePC project will lead onto new configurations of Windows that feature a capability of scaling up and down depending on hardware variations. Windows PCs and devices, in some user case scenarios, do not require full breadth of legacy Win32 application support. CorePC will enable different configurations of Windows to be installed on a custom basis.
