Personally, I like two things: 1) clean context menus and 2) media players other than Windows Media Player. There is a quick and easy way to to be rid of the 17 different buttons that WMP adds to your right click context menus.

Go to Start --> Run and insert regsvr32 /u wmpshell.dll



If for some bizare reason you wish to restore these items, run regsvr32 wmpshell.dll
