Announced in October 2019, Windows 10x is the operating system for the Surface Neo, a new kind of dual-screen device. It is a modified version of Windows 10 whose interface is specifically designed for this type of device. It has a new explorer, a revised Start menu and many other modifications. In general, it offers a different experience from that of the standard system.
Microsoft has launched a Windows 10x emulator that allows developers to adapt their applications to the new interface, which allowed developers to have an overview of how the system looks on dual-screen devices. A developer who’s name is Gustave Monce has just spotted a new image in the emulator which suggests that Microsoft is working on a version compatible with larger devices, but also equipped with a single screen.
