Microsoft has acknowledged issues with the August security update KB5121003 for Windows 11, affecting versions 24H2 and 25H2. Users reported problems such as game freezing, unexpected closures, and system restarts after installing the update. The issues are linked to drivers and software for specific RGB-enabled peripherals or components, particularly involving the inpoutx64.sys driver. Games mentioned include ARC Raiders, MARVEL Tōkon: Fighting Souls, and THE FINALS. Embark Studios has released a support guide suggesting users stop and remove the inpoutx64.sys service as a temporary workaround. Microsoft is investigating the issue but has not provided a definitive fix or patch timeline.
