WMPnetwk.exe started using 50% of my CPU

I'm not even using Windows Media Player on Windows 7 and I certainly haven't turned on any network sharing features so why is this service using up so much CPU?

Now disabled thanks to advice on the CNet forums here.

Some witty comments there too like "3. Uninstall Windows Media Player 11...I mean if after 11 versions it still doesn't work right then its probably not gonna is it!"
