Uninstalling Windows Media Player v.10

I would like to uninstalll v.10, then reinstall v.9., but can't figure a way to accomplish this. It seem MS doesn't allow this. I tried uninstalling from Add/Remove Windows Components. This seemed to only disable the desktop icon. Checking in C:/Program Files/Windows Media Player,
All the files seem to be still there. Clicked on the icon in the folder it still worked as usual. Short of formatting and starting over, it seems that we're stuck with v.10 whether we like it or not.
If anyone has solved this, I'd really like to know about it.
Thanks
