Quick Tip: how to remove all the garbage that accumulates in the right-click context menu in Windows Explorer after you make an update/upgrade to Media Player.
Example: I upgrade my home server to Windows Server 2003 Service Pack 1. It forces me to upgrade to Media Player 10. OK, sure, go ahead, whatever. But now when I right-click a media file I have to practically scroll through a long list of MP-specific fluff in order get what I want (usually Rename or Properties). Here's the fix:
Click Start, Run and type in regsvr32 /u wmpshell.dll
That's it! Unregister WMP Shell. It's so simple...
[UPDATE] For Vista, you'll need to run this command in elevated-mode.
