Windows 8 runs non-Metro applications in the desktop. By default, if a second instance of an already running application is started by typing its name and pressing Enter, Windows 8 just switches to the already running application. For example, if you have one window of Notepad open, running Notepad again from the Start screen by typing its name and pressing Enter switches you back to the Notepad window already open.
To indicate to Windows 8 to open a new instance of the application, use Shift + Enter instead of Enter.
