Just use ResHack. Open it, go to the Version Info group, and look at the strings there. They all say Windows Media Player or WMP or Microsoft. I've tested this on other programs; if you change the stuff in there, it will change the name. As far as I can tell, it should be displaying the way you want it to. (I can't check; it says I'm missing a .dll when I try to run it)
