I did not know why the Microsoft continuously using windows media player as a defaults players. this is a very old media player and the features of this players is also too old.
The Microsoft media players @9 series development kit is provided customise information to use windows media players ActiveX control and Microsoft try to enhanced the features and make user friendly of this series. its support for plug-ins that create visualisation effect and digital signal process task. so that user use the app in full mode of players.
As per my review the media players is also good for simple purpose and the features of to add more mp3 and mp4 in media players list is very nice in the comparison of other media players. this is one of the best features of windows media players.
Lastly, I am requesting to Microsoft media development team for developed better app or added another players like VLC as a defaults players in Microsoft windows.
