(Windows Key + R) Also try: 1. Right click Start Button 2. Click Properties 3. Click Customize for Start Menu 4. Scroll down and check RUN COMMAND. 5. Click OK and OK to apply
To add "run" to the start menu, go into Taskbar and Start Menu properties and you will find that it can be added under "customize" (both classic and vista style) on the start menu tab. The quickest way to get the properties dialog up (to me anyways) is to right click the taskbar and select properties.
