In the upper left corner is a button that when highlighted (hold mouse over it) says show menu bar. Click it. the menu bar has a help button. One of the help choices is about windows media player, which will tell you the version, which I think is what you want to know.
I have Windows Media Player installed on my HP computer with ME. How do I find out what series it is? I clicked on Properties but it didn't specify which series I had. Thanks.
