Windows specific registry snippet: This gist is useful for getting Console2 (http://sourceforge.net/projects/console) on right click of a folder, drive or background. This gist assumes that Console2 is installed and accessible from C:\Apps\Shells\Console2\Console.exe and the icon for the same is C:\Apps\Shells\Console2\Console.ico.
