    Latest Windows 11 Upgrade Terminates Intrinsic Support for AC-3 Codec

    In an unexpected turn of events, Microsoft has indicated the obsolescence of the intrinsic AC-3 codec support in the newest update of Windows 11, termed 24H2. This revelation emerged discreetly on a technical assistance webpage of the company.

    The pronouncement from Microsoft states, “Commencing with Windows 11, version 24H2, the AC-3 codec will be omitted from the operating system’s integral components.” It denotes that media dependent on this codec might encounter difficulties during playback on the native media software as well as on certain alternative media applications.

    Nonetheless, Microsoft concedes that a significant number of hardware producers customarily embed the AC-3 codec within their equipment. Thus, machines from these entities might uphold native support for AC-3. The reasons for Microsoft’s decision to excise the codec remains undisclosed on the support website.

    Patrons of alternative media software, like VLC Media Player, should not run into any disruption since these applications are equipped with their own codec arrays. Contrarily, legacy applications such as Windows Media Player necessitate the installation of the AC-3 codec on the machine to operate proficiently.

    Advice: To confirm if your media software is AC3-compatible, proceed to download and attempt to operate a file utilizing the AC3 format.

    For individuals utilizing an antecedent rendition of Windows 11, AC-3 formatted media should play smoothly on Windows Media Player and its antecedent variant.

    Caution: The ongoing compatibility status of the AC-3 codec ensuing an upgrade from a prior installation of Windows 11 to 24H2 currently lacks clarity.
