"This new experience allows users entering tablet posture to stay in the familiar desktop experience without interruption," said Microsoft.
Other changes have been made to improve the experience of the interface on a touch screen:
Increased spacing between Taskbar icons.
Search box on taskbar collapsed into an icon.
File Explorer switches to touch-optimised layout.
Touch keyboard auto invokes when you tap text fields.
Microsoft said that the new version is available to a limited number of Insiders while it evaluates the quality of the new interface.
It added that when using the laptop functionality of their 2-in-1 tablet, Windows will continue to function as before, and when the keyboard is folded back or removed, the new mode should automatically trigger.
