Windows 7
I am always open to anything that will allow me to work more efficiently. Way back in Windows XP, the various sysutils would install a context menu into Windows Explorer that would allow us to open the command prompt with the selected folder set as the current directory. ContextConsole Shell Extension is another tool which will do the same for the Windows 7 environment.
However, with Windows 7, you no longer need to install additional extensions and software. Instead, the context menu option, "Open command window here", is available by holding down the shift key and right clicking on the folder.
