If you're running Visual Studio 2008, I would highly recommend PowerCommands for Visual Studio 2008.
From their page on MSDN Code Gallery:
PowerCommands is a set of useful extensions for the Visual Studio 2008 adding additional functionality to various areas of the IDE.
Basically, it adds a number of menu items to the right-click menu in various areas of Visual Studio. My favorites are "Open Command Prompt", "Open Containing Folder", and the ability to modify recent files and properties. Head over to the MSDN Code Gallery page for full details.
