The Windows Mixed Reality platform is approaching an important lifecycle deadline. Microsoft has deprecated Windows Mixed Reality, removed it from Windows 11 version 24H2 and stated that existing devices can continue working with Steam through November 2026 when systems remain on the relevant Windows 11 version 23H2 release.
This creates a significant planning issue for organisations using PC-based Windows Mixed Reality headsets such as HP Reverb G2. The headset itself may remain physically functional, but its practical use depends on the operating system, Mixed Reality Portal, drivers and SteamVR integration around it.
What changed in Windows 11?
Windows Mixed Reality is not included in Windows 11 version 24H2. This affects Mixed Reality Portal and Windows Mixed Reality for SteamVR.
Microsoft’s guidance states that existing Windows Mixed Reality devices can continue working with Steam through November 2026 if users remain on the compatible Windows 11 version 23H2 environment. However, operating-system servicing dates also need to be considered. Windows 11 version 23H2 Home and Pro have already reached end of servicing, while Enterprise and Education support continues until November 2026.
Remaining on an older operating-system version purely to preserve headset compatibility may introduce security, support and compliance concerns. Any decision should therefore involve the organisation’s IT and security teams.
What this means for HP Reverb G2 deployments
Teams using HP Reverb G2 should audit where the headsets are deployed and what each workflow depends on.
Useful questions include:
- Which Windows version is installed on each connected workstation?
- Does the application require Mixed Reality Portal or SteamVR integration?
- Are the computers managed by an internal IT policy?
- How long must the current VR workflow remain operational?
- Are replacement headsets, cables or controllers required?
- Is there a tested migration path to another platform?
The key point is that hardware condition alone is no longer enough. Compatibility between the headset, workstation, operating system and software stack needs to be treated as one system.
Plan before the deadline
Organisations should avoid waiting until a routine Windows update interrupts a live training, simulation or visualisation environment. Document the current configuration, test alternative hardware where appropriate and establish whether spare units are genuinely useful within the remaining software lifecycle.
The XRDepot perspective
XRDepot can help organisations investigate replacement Windows Mixed Reality hardware and source legacy equipment where availability permits. We can also discuss alternative XR hardware when continuing with the existing platform is no longer practical.
Sourcing replacement hardware does not extend Microsoft or manufacturer support. Buyers should confirm their software, security and deployment requirements before placing an order.
