Windows Core OS Under Active Development, Will Support Win32, UWPs and PWAs Via Containers To Improve Performance, Size And Security

Windows Core OS or WCOS is not just alive but under active development, indicated Microsoft before hastily redacting the wordings in a support document. The simplified, optimized and highly secure version of a future iteration of Windows operating system is being developed to allow Microsoft the freedom of minimizing features and supporting elements of an OS that is extremely light.

Microsoft is still very interested in deploying a lightweight and unified Windows OS experience. Built on the core concept of Windows 10 OS, the Windows Core OS or WCOS will be another fork of the main OS. Just like the Windows 10X, the WCOS will eventually power a select class of computing devices.

Microsoft Accidentally Confirms Active Development Of WCOS Through Support Document:

Microsoft is actively developing Windows Core OS or WCOS. The existence of WCOS was inadvertently or accidentally confirmed by the company when it amended some older support documents. It appears Microsoft wants some clear guidelines that will govern the future development of the Windows OS. Hence the company may have been updating documents to ensure there are separate components for Windows 10, Windows 10X, and WCOS.

In a support document, Microsoft accidentally confirmed desktop fonts support for Windows Core OS. Realizing the accidental confirmation of an unannounced OS, Microsoft quickly modified the document to remove any and all mention of ‘WCOS’ and future devices.

“Please note: Not all of the Desktop fonts will be in non-desktop editions of Windows 10 such as Xbox, HoloLens, Surface Hub, future WCOS devices, etc.”

What Is WCOS And How Will It Be Different From Windows 10 and Windows 10X?

Microsoft hasn’t yet confirmed the existence of Windows Core OS. The company has, however, confirmed Windows 10X. The latter is meant for lightweight portable computing devices as well as multi-form-factor or foldable devices. Windows 10X is aesthetically and functionally quite different from Windows 10 OS. However, WCOS is expected to be fundamentally different as well.

Windows Core OS is certainly a much leaner version of Windows 10. It was previously believed that Microsoft might deploy WCOS on Smartphones after abandoning Windows Phone. However, the company merely adopted Android as the base platform and chose to deploy apps, software, and other services.

WCOS appears to be a fork of the traditional Windows 10 OS. It might not be touch-centric as it has composers/adaptable shells for all form factors. According to the job listings, preview builds and mentions of the same elsewhere, WCOS could show up on PCs, laptops, Xbox, dual-screen tablets, multiple screen devices, Surface Hub, Mixed Reality headsets, and also the Internet of Things (IoT) products. Simply put, Windows Core OS is being developed with a radically different way of interacting with computing devices.

Internally, WCOS has the ability to support a variety of app platforms. It is expected to run Win32, UWPs, and PWAs. The OS will ensure these sub-platforms are installed in isolated virtual containers. Essentially, Windows Core OS could eventually be the choice of OS which requires a highly secure environment and a very select number of functions to be performed reliably and consistently. Microsoft appears to be developing WCOS as a locked and stripped version of Windows 10. Such a controlled version might not be meant for the average PC user, but will immensely help those who require performance and security in special applications.
