This is a media player which is provided by the Microsoft with its Windows operating system. The features of this media player is very limited, most of the file does not play with this media player.
This media player does not support subtitle track. But the picture quality and the audio quality is quite better than other media players. I use this only for audio player. Its good for audio but not good enough for the video. As this is a default media player of Windows so every Windows user knows about it very well. But I think this media player need huge upgradation.
