Windows allows you to have multiple programs open at any one time. Each program is said to be open in its own window. Jumping between these open files is accomplished easily by minimizing (hiding the window out of sight), maximizing (open to full your whole screen), restoring (putting a maximized or minimized window back to its previous size), or closing the open windows.

You will find the Minimize, Maximize, Restore and Close buttons on the horizontal title bar at the top of each window. Each action can be accomplished from the title bar icons, the control menu icon, or by right-clicking the title bar.
