How cool is this? You can now open a Command Prompt for any directory in Vista without having to download a Powertoy (like the one available for Windows XP). However, they do keep it hidden to protect users from, well, themselves. All you have to do though is hold down the Shift key and right-click on a folder (if you just right-click without the Shift key you will not see the option):
If you are trying to open a Command Prompt for a networked address it will automatically map the network drive so that there is a valid path for it to open. It’s great to see Microsoft implementing some of the Powertoys right into Vista but why are there no virtual desktops yet?
