Existing Windows Mixed Reality devices will continue to work with Steam through November 2026, if users remain on their current released version of Windows 11 (version 23H2) and do not upgrade to this year’s annual feature update for Windows 11 (version 24H2).
Tldr: fuck you, if you want to use your hardware, bend over and spread your cheeks cuz your OS is gonna be raw digging the security vulns we’ll be releasing over the next 2 years.
