Run command shortcut deleted

i searched for 'run' in start menu and dragged it to the desktop to form a shortcut. then i dragged the shortcut run icon to the start button to pin it to the start menu. later i quickly shift deleted the shortcut on the desktop and it stopped working. the run command doesn't appear on start menu search or anywhere. please help to get the program back. "right click on start menu -> customize -> run command on" is not working.
