🚨Windows 11 26H2 Hit by AC-3 Audio Bug

Old Apps Crash on New Windows Update

TL;DR

Windows 11 26H2 users face an AC-3 audio bug causing app crashes. Older applications are hit hardest, with no fix available yet. Uninstalling is the only current solution.

Windows 11 26H2 users are dealing with a new AC-3 audio bug that causes applications to crash or fail to start. This issue primarily affects older applications that rely on the AC-3 decoder, which is less common in modern apps. If you're running legacy software, you're in for a rough ride. Microsoft hasn't provided a fix yet, and uninstalling the update is the only workaround. The bug also appears in earlier versions of Windows 11, and Microsoft is tight-lipped about a timeline for a resolution. This isn't the first audio issue with this update, and it's part of a string of problems for Windows 11.
