Following feedback from numerous gamers, Microsoft is officially investigating Windows 11 gaming issues that emerged after installing the August cumulative update. These severe complications affect Windows 11 versions 24H2 and 25H2, impacting popular titles such as Arc Raiders, Marvel Rivals, and The Finals.
A Multitude of Gaming Anomalies
Based on player reports, the affected games may exhibit severe graphical glitches and frequent stuttering after successfully loading. Furthermore, users experience unexpected system reboots and pop-up errors displaying “EXCEPTION_ACCESS_VIOLATION,” rendering the games virtually unplayable.
Upon receiving this feedback, Microsoft published an official update log stating that their engineering team is actively investigating the root cause. They are working to determine whether the culprit lies within the Windows 11 codebase, the games themselves, or conflicting third-party components. Currently, without a definitive conclusion, affected users may need to temporarily uninstall the August update to restore stability.
Strengthened Kernel Handle Validation
Some players speculate that this instability directly correlates with the security enhancements deployed in the August cumulative update. During this cycle, Microsoft addressed a staggering 400 security vulnerabilities, including two zero-day exploits previously disclosed by security researchers.
Within this massive security overhaul, Microsoft significantly reinforced the Windows NT kernel handle security validation to elevate overall system integrity. Consequently, these stringent security modifications might disrupt specific games that rely on more lenient validation protocols. Ultimately, the community must await the findings of the ongoing investigation. In all likelihood, game developers are already collaborating closely with Microsoft to resolve this disruptive issue.
