Microsoft is also partnering with Valve for VR on Windows 10

Context & Ripple Effects
By mid-2015 Microsoft had already staked out mixed reality from the device side, bringing Xbox games to the HoloLens headset months earlier. The Valve partnership flips that around: instead of Microsoft-only hardware, Valve's PC VR stack gets a home on Windows 10 itself.
That set up the platform play Microsoft made explicit a year later when it opened Windows Holographic to partners like Intel, AMD, HTC, and Acer, then committed at Intel's dev event that every new Windows 10 PC would work with head-mounted displays. Valve as the first named software partner gave that open-platform pitch immediate credibility.
First-order effects
- Valve gains a native OS-level partner for VR on Windows 10, reducing its dependence on self-built runtime plumbing to reach mainstream Windows gamers.
- Microsoft gets the dominant PC VR content ecosystem anchored to Windows 10 ahead of its own headset hardware arriving through partners.
Second-order effects
- HTC, which was shipping Valve-cooperative Vive hardware in this era, becomes both a Windows Holographic partner and part of the Valve orbit — giving Microsoft two routes into the same headsets.
- Oculus-style closed ecosystems face pressure as Windows 10 positions itself as the neutral OS layer where any headset vendor can run Valve's VR content.
Third-order effects
- If the pattern held — and the later announcement that Steam VR, Minecraft, and Halo are coming to Windows Mixed Reality suggests it did — PC VR consolidates around an OS-plus-store structure where Microsoft controls the platform layer and Valve supplies the content catalog.
- That division of labor anticipates today's mixed-reality market shape: hardware commoditized across OEMs like Acer, platforms owned by OS vendors, and storefronts contested separately.
The trend: PC virtual reality is settling into a layered structure where operating-system vendors like Microsoft supply the platform while content gatekeepers like Valve supply the games.
