Quickly Displaying Your Desktop from Open Windows
If you have multiple windows open and want to display your Desktop, you’d have to minimize each window to display your Desktop.
To quickly display the Desktop without having to manually minimize all your open windows, and keep those windows (applications) open at the same time, just right-click on the Start button, then select Desktop from the drop-down menu.
Your Desktop will be displayed with all your open windows minimized, as shown in the example below. (The minimized items will be shown in the taskbar with a line underneath them.)
