How do I make Windows Media Player the default player for a file type?
In Windows Media Player 7, you can do this on the Format tab of the Options dialog box. In Windows Media Player for Windows XP and Windows Media Player 9 Series, this option is available on the File Types tab of the Options dialog box. You must be logged on as an administrator or a member of the Administrators group to change the list. If your version of the Windows operating system supports the AutoPlay feature, your AutoPlay settings may affect your Player file types settings. For more information about AutoPlay, see Windows Help. If you install other players on your computer, they may interfere with your Player file types settings. For more information about setting file type ownership in other players, see the documentation that came with those programs.
