Microsoft is reducing the functionality of Windows Media Player Legacy in the latest update, Windows 11 Experimental Build 29648.1000, by restricting caption controls. Users can no longer enable captions in the legacy player and are prompted to switch to the modern Media Player instead. This change was first noted by Windows enthusiast Xeno Panther and indicates a deliberate move by Microsoft to encourage users to adopt the newer application.
In the previous Experimental Build 26340.9212, captions were still operational, but the latest build has removed options for Off and Defaults, leaving only "On if available." When attempting to activate captions, users receive a message stating that captions cannot be enabled in Windows Media Player Legacy.
The modern Media Player does offer enhanced caption customization features, such as font size and color adjustments, but it has been criticized for its performance issues. The modern app takes longer to open videos and consumes significantly more RAM while idle compared to the legacy version. Additionally, the modern Media Player requires users to purchase HEVC Video Extensions to play HEVC files, which the legacy player supports without additional costs.
Despite these changes, the Legacy Media Player still retains features like library view and CD burning, and it remains an optional feature in Windows 11. Microsoft has previously removed other functionalities from the legacy player, such as the Sync tab in 2023. As users look for alternatives, third-party open-source media players like VLC and mpv are becoming more popular, with mpv recommended for its performance and minimal interface.
