Microsoft has begun rolling out a permanent solution to a problem causing system crashes and gaming disruptions on Windows 11 devices, specifically related to game launch failures and freezing with "EXCEPTIONACCESSVIOLATION" errors. The issue affects various games, including ARC Raiders, MARVEL Tōkon: Fighting Souls, and The Finals, particularly on Windows 11 versions 24H2 and 25H2, and is linked to peripherals with built-in RGB lighting. The inpoutx64.sys driver has been identified as the cause of these complications. Microsoft is deploying a fix that disables this driver on affected devices, starting on August 26, 2026, and it may take up to 24 hours to reach all impacted devices. This driver block will also be included in the September 2026 Windows security updates. For enterprise-managed devices that do not automatically receive the fix, a temporary workaround involves disabling the inpoutx64 driver via the Windows Registry. Microsoft has stated that disabling this registry key should not lead to unintended behavior.

Microsoft has identified RGB peripherals and components as the source of game crashes following the August 11 Patch Tuesday rollup for Windows 11. The issue stems from drivers or code components resembling inpoutx64, which are triggered when certain games are launched. Embark Studios linked the problem to update KB5121003, and Microsoft confirmed the connection to inpoutx64.sys, although the root cause involves changes to the Windows kernel driver. A temporary workaround involves editing the registry to disable the inpoutx64 driver, though this may affect RGB functionality. Affected games include ARC Raiders, MARVEL Tokon: Fighting Souls, and The Finals on Windows 11 versions 24H2 and 25H2, with symptoms like game freezing and unexpected closures. Rolling back the update is not recommended due to security vulnerabilities it addressed. The inpoutx64.sys driver has been included with various RGB and monitoring software, and Microsoft is investigating the issue further, asking users for feedback. No timeline for a permanent fix has been provided.

Recent reports indicate that the hardware monitoring tools HWMonitor and CPU-Z have been compromised, leading to users downloading malware instead of the legitimate software. Users reported receiving suspicious executable files and antivirus alerts when attempting to download the latest versions. A specific incident involved a user who downloaded HWMonitor from the official CPUID website, only to find the file was labeled incorrectly and flagged as a virus by Windows Defender. Cybersecurity experts confirmed that this is a serious issue involving a multi-stage trojanized attack from a compromised domain. The developer of CPU-Z and HWMonitor acknowledged that a secondary feature linked to the website was compromised for about six hours, causing the main website to display incorrect files. Users are advised to refrain from downloading or updating these utilities until the issue is resolved.

The Windows 11 September 2025 Update (KB5065426) has faced installation errors and Digital Rights Management (DRM) issues affecting video playback, although Netflix remains unaffected. Microsoft traced these problems to the previous optional update, KB5064081 from August 2025, impacting users of digital TV and DVD applications that use the Enhanced Video Renderer with HDCP enforcement. Additionally, some Electronic Arts (EA) games have malfunctioned after the August and September updates, particularly those using the Javelin anti-cheat engine. Users have reported rendering issues in DirectX 9 games, disrupted Microsoft Ink services, and ongoing PowerShell functionality problems. The update has also been linked to issues with Server Message Block (SMB) v1, affecting file sharing and connectivity. Microsoft is working on solutions for these issues.
