As you may know, Windows Core OS is the core operating system for many future variants of Windows.
One of those is Windows 10X, the operating system that would become the primary operating system of Dual Screen devices initially.
Microsoft has recently announced that because of the Novel Coronavirus outbreak, plans to release Windows 10X for the Surface Neo and other dual-screen devices will be postponed and they will now focus on building the operating system for existing single-screen devices.
One of the mayor advantages of Windows 10X is also its Achilles heel.
It will run Win32 applications in containers, where only Modern apps will run native in the operating system.
This reduces the attack surface of the operating system since every application is sandboxed.
They also will be able to service the operating system faster and more reliably.
Some even say that a simple reboot will suffice for Windows 10X, since the operating system can fully install the update in the background (like it does on Chrome OS devices).
This would be the best of both worlds: better battery life, a more secure operating system, fast servicing, more reliability (a win32 app will in the worst case crash the container it is running in), and still support for Win32 apps.
Let’s be honest, only Win32 apps will be able to crash the entire operating system.
However, the big issue here is that it will be emulating an operating system for those containers, as we all know this reduces performance in some way.
This really shows that Microsoft is still working towards a future where Win32 apps are history.
