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, versions 1809 and newer, and Windows 11: Mixed Reality Portal is updated via the Microsoft Store app. More information can be found on the Get Mixed Reality Portal page.
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 and Windows 11 contain key OS components and technologies that enable Windows Mixed Reality

Using Windows Mixed Reality in SteamVR requires the following software:

6. SteamVR, developed and maintained by Valve Corporation that enables virtual reality apps and games on Steam. More information can be found here
7. 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:

8. 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.
