Windows 10X is a new version of Windows 10 designed for dual devices screen such as Microsoft's upcoming Surface Neo, which will be available from 2020. The “new” operating system will feature a custom UI for these devices.
Windows 10X is Windows
At the Surface event, Microsoft said that Windows 10X will "support Windows applications", which means that all traditional Windows graphics applications will work just like Windows 10 Home or Professional. It's not a completely new operating system, but a custom version of Windows 10 with a UI designed for foldable devices.
Microsoft told The Verge that Windows 10X will run traditional Windows desktop applications in a container to improve duration battery life. Windows 10X appears to be based on Windows Core OS.
Optimized for dual-screen devices
Windows 10X has a UI "designed and optimized for dual-screen devices, such as the Surface Neo," according to Microsoft.
Surface Neo is a dual-screen device that opens like a laptop. Alternatively, it's like two tablets connected together by a joint.
There will be no Live Tiles
Part of optimizing the operating system for dual-screen devices seems to be removing Live Tiles. There is a new Start menu with simple icons.
Dual-Screen Tweaks
When you launch an app, it will launch on one side of the device. It's a bit like Windows 10's Snap feature – apps will open on one screen (or one side of the device) rather than both screens. You can drag the app window to the middle of the screen to display it on both screens. Microsoft says that this will not only make the application window larger on both screens, but will also "optimize" theconnection of the app so that the app can intelligently take advantage of both screens.
Windowws 10X and dual-screen devices are not currently available. Microsoft will release Windows 10X before the release of the Surface Neo, so developers will have time to try it out and optimize their applications for the new OS.
Microsoft posted on blog one article for the upcoming Windows 10X, but didn't mention many technical details.
