Does this support windows mixed reality headset?

Yes and no. WMR can use it through SteamVR. But Freedom Locomotion was built in a version of Unreal which had a hand flipping bug - a 50/50 chance of loading the left hand as the right hand - which never posed a problem for the Vive due to the symmetrical nature - but will do for the WMR controllers which are asymmetrical and mirrored copies of each other.
