RGB lighting setups may be causing system instabilities on Windows 11, particularly during gaming sessions, as reported by Microsoft. The issue affects PCs running Windows 11 version 25H2 or newer, especially after the August 11 KB5121003 update, and is linked to driver or code components associated with 'inpoutx64'. Users have experienced 'ExceptionAccessViolation' blue screens, which occur when software accesses memory outside its designated boundaries. The problem may be related to anti-cheat technology in various games conflicting with RGB software. Affected titles include Arc Raiders, Marvel Tokon: Fighting Souls, and The Finals. Microsoft and game developers are working on solutions and recommend temporarily disabling inpoutx64, which may result in loss of RGB functionality. The issue also affects internal RGB components.
