While there are some third party apps for Windows Phone and Windows that allow FLAC playback, it’s unfortunately not something that is available in Windows Media Player. Yet. But it’s coming to Windows 10 Technical Preview.

This is a very good thing to bring to the preview software, and something that users have been wanting for quite some time. The ability to play more media file types allows for a more free and open way to enjoy favorite songs and is definitely on the side of the user.
