早前本站報導過Windows 10將會原生支援MKV影片格式播放，但是Windows 10在明年才正式推出那對Windows RT平台來說Windows Store上又沒有一個十分好又能夠播放MKV的播放器。不過作為原生的XBox Video在最近的更新上加入了對MKV影片格式的支援，讓Windows RT的用戶不用等待VLC播放器或Windows 10了。
Support for MKV videos (the extension used for the Matroska Media Container). The update supports playback of most MKV files as long as they contain streams that use codecs supported by the app. For more information on MKV support on Windows, please check out the related article about support for MKV on Xbox One. The implementation is the same on both platforms except that V_MPEG2 is only supported on the console.
