The toolbar has probably been re-positioned off of the screen. To retrieve the toolbar, minimize Microsoft Word, click with your right mouse button on the Windows desktop and choose Properties from the pop-up menu. The Display Properties window will now appear. Click on the tab that says Settings and then find the slide bar for the screen resolution (it can also say screen size, desktop area, etc. depending on your version of Windows). The slide bar will also have a setting such as 800 by 600 pixels, for instance. Move this slide bar to either increase or decrease the size of your desktop and then click on the Apply button. When the screen is re-sized and if you are asked if you want to keep this setting, click on the Yes button. Next, click on Microsoft Word on your taskbar to bring the program back up and you should see your toolbar. Once you have the toolbar positioned where you would like to have it appear, minimize Word and you can restore you original setting for the screen size on the Display Properties window.
