Windows 11 software and security issues

Overview

Windows 11 users have encountered various technical difficulties regarding security tools and system updates. Initial reports focused on troubleshooting Windows Defender failures and managing automatic driver updates. Subsequent reports indicated Microsoft Defender scans often stall at 90% or 95% progress due to specific combinations of application versions and security intelligence updates.

Microsoft is investigating the August 2026 security update, KB5121003, which addressed over 400 security vulnerabilities but has been linked to significant gaming disruptions. Affected users, primarily on Windows 11 versions 24H2 and 25H2, have reported games becoming unresponsive, abrupt application closures, ‘EXCEPTION_ACCESS_VIOLATION’ errors, and unexpected full system reboots. Specific titles identified include ‘The Finals’, ‘ARC Raiders’, and ‘MARVEL Tōkon: Fighting Souls’.

Microsoft has identified a link between the KB5121003 update and instability caused by interactions with peripherals or internal components featuring RGB lighting. These devices often install drivers or code components with file names similar to ‘inpoutx64.sys’. Embark Studios, the developer of ‘ARC Raiders’ and ‘The Finals’, confirmed the issue relates to changes made to the Windows kernel driver affecting the ‘inpoutx64.sys’ file. While Microsoft works toward a permanent resolution, Embark Studios has suggested a temporary workaround involving the removal of the problematic file via the Windows command prompt to restore stability.
