Microsoft confirmed that a bug in the September 2026 update KB5124010 causes crashes in legacy applications using Dolby Digital AC-3 audio decoding. The issue affects Windows 11 versions 24H2, 25H2, and 26H2, with no immediate fix available. Modern apps are largely unaffected, but legacy software may fail to launch or close unexpectedly when audio features are used.
Microsoft has confirmed a bug in Windows 11 updates 24H2, 25H2, and 26H2 that causes some games and applications to crash when using built-in AC-3 (Dolby Digital) audio decoding. The issue stems from the September 22 optional update, KB5124010, and affects legacy software relying on Windows' native audio components. While modern apps are largely unaffected, users may experience sudden closures or launch failures when adjusting volume or enabling audio features. Microsoft is working on a fix but has not provided a timeline.

Microsoft has released optional updates to address critical bugs introduced by the September 2026 Windows security patches, specifically targeting failures in the File History backup feature and Always On VPN connections. While the mandatory September 8 update (KB5124008) caused widespread issues, including broken backups and failed remote access, Microsoft has since provided workarounds and partial fixes. The File History bug, which prevented backups and displayed false error messages, is addressed by optional updates KB5124010 and KB5124006, though some functionality remains impaired. Meanwhile, Always On VPN issues, where connections stall or fail due to protocol conflicts, require administrators to manually switch from automatic protocol selection to a single protocol (SSTP or IKEv2). These issues are part of a broader pattern of problems caused by the September updates, including Remote Desktop failures and audio glitches, which Microsoft is continuing to resolve through out-of-band and optional releases.
