One of the best utilities that I have been using recently is StExBar. It's a great utility that comes from Stefan's Tools ( http://tools.tortoisesvn.net/ ). From the site:
The StExBar provides many useful commands for your everyday use of Windows explorer. And you can add as many custom commands on your own as you like.
Have you ever needed to open a console window while you were using the explorer? And to have that console already set to the directory you're showing in explorer right now? Well, StExBar provides that with one simple mouseclick. There's also a hotkey defined for this: simply press Ctrl-M to open the console.
It does a bunch of other great things as well.
