Mixed Reality software overview and release history

Introduction to Mixed Reality software

Windows Mixed Reality consists of the following major software components:

  1. Mixed Reality Portal, which provides the main Windows Mixed Reality experience
    • In Windows 10 versions 1709 and 1803, Mixed Reality Portal is a key component of the Windows 10 operating system updated via Windows Update.
    • In Windows 10 version 1809 and newer, Mixed Reality Portal is updated via the Microsoft Store app.
  2. The Mixed Reality feature-on-demand package (FOD), automatically downloaded and installed during Mixed Reality Portal's first-run. More information about the FOD package can be found here
  3. The Mixed Reality headset and motion controller driver, also known as the HoloLens Sensors driver, is the key driver package that enables Windows Mixed Reality headsets to work with Windows Mixed Reality. This is automatically downloaded and installed via Windows Update the first time your Mixed Reality headset is plugged in, and is regularly updated via Windows Update
  4. The **Mixed Reality motion controller model drivers contain the 3D models of the Mixed Reality motion controllers and needed for third-party Mixed Reality experiences. This is automatically downloaded and installed via Windows Update the first time your Mixed Reality motion controllers are paired to your PC, and is updated via Windows Update
  5. Windows 10, version 1709 (the Fall Creator's Update) or newer contains key OS components and technologies that enable Windows Mixed Reality

Using Windows Mixed Reality in SteamVR requires the following software:

  1. SteamVR, developed and maintained by Valve Corporation that enables virtual reality apps and games on Steam. More information can be found here
  2. The Windows Mixed Reality for SteamVR component, which bridges SteamVR with Windows Mixed Reality. More information about this component can be found on the Windows Mixed Reality for SteamVR page

Managing your Windows Mixed Reality headset:

  1. The Device Companion App, developed and maintained by each of the headset manufacturers, provides a quick introduction to your Windows Mixed Reality headset. On headsets with built-in Bluetooth capability, the Device Companion app enables restoring Motion Controllers to their factory Bluetooth pairing. Some headsets (such as the Samsung Odyssey, and Samsung Odyssey+) also use the Device Companion App to deliver headset firmware updates from the headset manufacturer. This app is downloaded automatically the first time your headset is plugged in and can be found in the Windows Start Menu.

Windows 10 release notes - May 2020

The Windows 10 May 2020 Update (v2004) includes new features for Windows Mixed Reality (VR) headsets, such as the ability to launch Win32 applications in the mixed reality home. HoloLens (1st gen) is in Long Term Servicing (LTS), with servicing updates to be released monthly.

Upgrading to the latest PC release for Windows Mixed Reality immersive (VR) headsets, open Settings > Update & Security and select Check for updates. On a Windows 10 PC, you can also manually install the Windows 10 May 2020 Update using the Windows media creation tool.

Latest release for Desktop: Windows 10 v2004 (10.0.19041.264)

Updates for Windows Mixed Reality immersive headsets

Introducing the new Microsoft Edge

As previously announced, we've made updates to better support using the new Microsoft Edge browser in Windows Mixed Reality. The new Microsoft Edge adopts the Chromium open-source project to create better web compatibility for customers and less fragmentation of the web for all web developers. It also supports WebXR, the new standard for creating immersive web experiences for VR headsets, in place of WebVR.

Improved Settings for WMR

Thanks to your feedback, we've added and clarified settings on the Headset display page:

  • Visual quality of my home - changing these settings affects only the mixed reality home environment (Cliff House and Skyloft):

  • Adjust level of detail and quality of effects in the mixed reality home - this changes some of the rendering affects we use in the home. In particular, the visual quality of different materials (wood, concrete, and so on) will scale as you change this setting from low to high.

  • Change app window resolution - by default, most 2D windows launched in the home are launched with a 720-p resolution. While you can manually resize them horizontally & vertically, you can also opt to have them all launch at 1080p instead. Previously this option was available as the Very high (beta) option under Visual quality. We've appropriately split it out as a separate setting now.

  • Experience options - these options adjust the mixed reality experience to reduce load on systems where the hardware might struggle to keep up with an unrestricted 90 fps. You can explicitly enable or disable these additional settings, or choose Let Windows decide and let our heuristics continue deciding when to toggle these on and off.

  • Resolution - if you have a high-resolution headset like the HP Reverb, we support running it at its native resolution, or at a reduced resolution for performance reasons. Earlier headsets, like the Samsung Odyssey and Odyssey+, only support a single resolution so you can't change this setting on those headsets.

  • Frame rate - you can now manually set the frame rate of the headset display, or continue to let Windows use its heuristics to determine if 60 Hz or 90 Hz is more appropriate.

  • Calibration - as before, you can adjust your IPD (interpupillary distance) if supported by your headset.

  • Input switching - toggle the input focus switching (Win+Y) behavior to be automatic (based on presence sensor feedback) or manual.

New Cortana app

This update to Windows includes the latest version of the Cortana app, which is currently US English-only and no longer supports certain mixed-reality specific commands such as "Take a picture" and "Take a video." You' can use the new Cortana to launch apps, and it also supports new productivity focused commands like, "When's my next meeting?" or "Send an email to that I'm running late."

Additional updates in available in 19041.546 (released October 2020)

This desktop monthly servicing update includes the following changes for Windows Mixed Reality devices:

  • Reduces distortions and aberrations in Windows Mixed Reality head-mounted displays (HMD).
  • Adds support for upcoming HP Windows Mixed Reality motion controllers.
  • Changes the behavior of the 90-Hz refresh rate setting in Windows Mixed Reality to no longer automatically switch back to 60 Hz in certain cases when 90 Hz cannot be achieved.

Help us improve!

We continually look to improve compatibility. If you find your favorite classic Win32 application not behaving correctly while in Windows Mixed Reality, submit feedback via our Feedback Hub.
