Microsoft is working on a mysterious "Windows Core OS" project that will unify Windows across all devices, and a "Polaris" desktop. We know the following.
Note that Microsoft has not officially announced these projects yet. Windows Core operating systems, C-Shell, and Polaris may change dramatically before publishing or will never be released.
Microsoft wants OneCore
Microsoft wants a unified operating system for all Windows devices from Windows 1
A Microsoft project called "OneCore" today means that Windows 10, Windows Server, Xbox 10, Windows 10 Mobile, Windows 10 IoT, and the HoloLens operating systems are all based on the same principle. Operating system ".
With the release of the anniversary update, two years ago, the proceedings were initiated. Since then, just like Windows 10, the Xbox One operating system is based on OneCore.
Although these are based on the same core, these operating systems still differ from this core.
Windows core operating system is a single operating system for all devices
Microsoft would like all Windows devices to be based on the same operating system and operating system Windows Core operating system. A Microsoft job listing on LinkedIn indicates that Windows Core OS (WCOS) will be "the operating system shared by all new devices". The same Microsoft job offer also calls Windows Core OS a "new operating system," according to Microsoft's OneCore team.
Zac Bowden of Windows Central spoke to Microsoft in early 2017 about Windows Core OS. This is how they described it:
Windows Core OS (WCOS for short) is a new, modern version of Windows and is a monumental step in turning Windows into a truly universal operating system. In short, WCOS is a common denominator for Windows that works cross-platform on any device type or architecture, and can be extended with modular extensions that provide functionality and experience for the devices.
Windows Core OS is the next step in Windows 10 is completely modular. It is a single base operating system for all devices. Instead of Windows 10, Windows 10 Mobile and the Xbox operating system based on OneCore, but still different, all Windows Core operating systems will run.
According to Mary Jo Foley of ZDNet, Windows Core operating system does not run natively Win32 applications – in other words, traditional desktop software. It runs UWP (Universal Windows Platform) apps. However, Windows Core OS is modular. Support for classic desktop applications could and should be added as a module. However, support for traditional software is not a core part of the system.
As Foley points out, Windows Core OS was formerly known as AndromedaOS in Microsoft. This is because the device may be started on the alleged "Andromeda" mobile device that Microsoft is working on, which may include two screens. It was rumored that this device was introduced in 2018, but Foley writes that Microsoft has gone back to the drawing board. It may never be published, so do not hold your breath.
In any case, work will continue on Windows Core OS. On October 11, 2018, Aggiornamenti Lumia found the first signs that Windows Core operating system applications had arrived at the Microsoft Store.
C shell is a modular interface
Composable shell, also called C shell or CShell, is another Windows core operating system project project.
Currently, devices that run Windows variants all have their own interfaces built into their unique operating system. Desktop PCs have the desktop, the Xbox One has the Xbox Dashboard, and Windows Phones have a phone interface. These are all separate interfaces and part of the respective operating system.
C shell becomes a shared shell (interface) running on Windows Core OS. It is a modular shell for a modular operating system. The shell can adapt to the device type in real time. In other words, Microsoft can create a user interface that automatically and automatically adapts the device you use to your needs.
For example, a future Windows phone might have a phone interface, but a full Windows window will provide desktop when docked to a keyboard and monitor. This would be a more powerful desktop than the limited Continuum for Windows 10 Mobile included Phones "- Desktop. A gaming device might someday switch between the Xbox One dashboard and the Windows desktop.
Currently, none of this can happen. The Windows desktop is part of Windows 10, the Xbox Dashboard is part of the modern Xbox operating system, and the phone interface is part of Windows 10 Mobile. However, C-shell means that each device can only run Windows Core OS, and C-Shell also provides the proper interface.
C-Shell was already running on a Windows Phone in 2017 in Windows Central. It looks pretty similar to the current Windows Phone interface, which shows what Microsoft is trying to do. Microsoft is not trying to reinvent the wheel or make any significant changes to the user interface.
Polaris is the desktop shell for C Shell
C shell contains several "composers", one for each interface type. Polaris is a composer who provides a desktop shell. In other words, it's a Windows desktop experience based on C-Shell and Windows Core OS. This is a major change from the past as Microsoft rebuilds the Windows desktop experience with modern code.
Other project names include Andromeda for the mobile UI, Aruba for the Surface Hub, and Oasis for Windows Mixed Reality devices like the HoloLens.
Polaris will be the biggest challenge for Microsoft, as a Windows core operating system with a Polaris desktop is likely to need to run the traditional Windows desktop software (Win32).
This is for new devices only  Do not worry: you will not be forced to upgrade. According to LinkedIn's LinkedIn jobs, this operating system is designated as "new devices." In other words, Microsoft will not suddenly upgrade your existing Windows 10 PC to Windows Core OS with Polaris.
According to Windows Central, this is the beginning The release of Windows Core OS will focus on mobile devices. For example, Microsoft may release "Surface Phone" with Windows Core OS and C shell. It would mostly use a mobile composer (Andromeda) and a desktop composer (Polaris) when docked.
In the long run, however, all new Windows devices could run this software – even desktop and laptop PCs. It looks like the future of Windows.
