Windows Mixed Reality

This Redstone 5 preview also introduces a few improvements for Windows Mixed Reality, including apps running in Mixed Reality can now make use of the Camera Capture UI API to capture images of the mixed reality world using the system capture experience.

Some adjustments have been made to the mixed reality video capture experience to make it easier to stop videos from the Start menu.

Also, it no longer requires a physical monitor to be connected while running Mixed Reality in cases such as backpack PCs.
