Microsoft's update for Windows 11, designated “KB5121003,” has caused issues for users with RGB peripherals, leading to system freezes, game crashes, and Blue Screen of Death (BSOD) errors. The problems are linked to drivers associated with RGB lighting, particularly a driver named “inpoutx64,” which disrupts system stability when certain games are launched. Affected games include Arc Raiders, Marvel Tokon: Fighting Souls, and The Finals, with BSOD errors citing “EXCEPTIONACCESSVIOLATION.” Microsoft has suggested a workaround involving temporarily disabling the inpoutx64 driver via the Windows registry, but users are cautioned about potential complications. Disabling this driver may affect the functionality of RGB features on peripherals, and re-enabling it carries risks as well.
