Microsoft revealed a new expression of Windows 10 at today’s Surface event, called Windows 10X.

This new version of Windows is optimized to work with dual-screen devices, such as the Surfaces Neo and Duo, also announced at the same event.

Windows 10X was introduced in tandem with the new Surface Neo, Microsoft’s dual-screen device, and presumably it’ll also work with the Surface Duo phone, also revealed at the event.

According to Microsoft, it allows all apps to make the best of both screens, or, as they put it, “to fuel a new era of productivity and creativity across two screens.”

Applications can be “spanned” across two screens, optimizing the layout so that it’ll work on both.

It’ll also reflow the layout depending on your screen orientation.
