Microsoft offers registry workaround for Windows 11 game crashes
Microsoft provided a temporary fix for game crashes and freezes on Windows 11 24H2 and 25H2 caused by August 2026 updates. The issue is linked to RGB device drivers, specifically inpoutx64.sys, which trigger problems when launching certain games like The Finals and ARC Raiders. The workaround involves disabling the driver via the Windows Registry, but users should back up the registry first.
The gaming disruptions trace back to the August 11, 2026 Patch Tuesday release, specifically KB5121003, which triggered crashes, freezes, and EXCEPTION_ACCESS_VIOLATION errors on Windows 11 24H2 and 25H2 systems. Microsoft's investigation identified RGB lighting device drivers, particularly inpoutx64.sys, as the culprit, with Embark Studios confirming that kernel driver changes caused the incompatibility.
The registry workaround requires users to set the Start value to 4, disabling the driver, though this may break RGB lighting functionality. Microsoft continues investigating the relationship between these components and affected titles like The Finals and ARC Raiders, while also noting this isn't the first time Windows updates have caused gaming stability problems, citing previous compatibility holds for Auto HDR and various game titles.
This issue could affect a significant portion of PC gamers using RGB peripherals, potentially forcing them to choose between lighting features and game stability. The temporary registry fix may create confusion among less technical users, though Microsoft's clear instructions and backup guidance could mitigate this. The recurring pattern of Windows updates breaking games may erode user confidence in timely update adoption, potentially leading some to delay security patches.
