Closing several applications in one step(Windows XP, Vista, 7)

             You often open several applications when working on the PC. You want to close the programs again at the end of a long session. It is quite annoying that you have to close each application individually.
            For closing several applications in just one step, keep the [Ctrl] key pressed when you select the icon buttons of the programs to be closed in succession in the taskbar. Then leave [Ctrl] and right-click the last select pushbutton. Select ‘Close group’ in the context menu. Windows now closes all the selected applications at once automatically.
