Windows 10: Microsoft movies and TV app question

Is the Microsoft movies and TV app only for windows 8 or 10? I found out windows 7 works better on my netbook but I miss the Microsoft movies and TV app.
Or is there another way to watch videos purchased from Microsoft and also another way to watch videos I got downloaded such as MP4 movies?

Sorry, Movies & TV is a Universal Windows App, so can only run on Windows 8 and above. The VLC Media Player is a well respected free media player that can play most anything. It works fine in Windows 7 (and Windows 10, come to that).
