Windows 11 26H2 blighted by new audio issue

Windows 11 26H2, along with 25H2 and 24H2, has a new AC-3/Dolby Digital audio bug that can crash or prevent older apps from starting, especially legacy games, media players, and productivity software that rely on Windows' built-in decoder. For CIOs and IT leaders, this is another example of how a routine update can create operational disruption, increase help desk demand, and force more cautious rollout and validation of Windows patches across mixed application estates. With no fix or mitigation available yet, organizations may need to weigh patching benefits against user impact until Microsoft ships a resolution.
