One of the most powerful things about Windows is that you can open more than one window or program at once. This means, however, that the desktop can get cluttered with many open windows for the various programs. A button appears on the taskbar for each open window. If there isn’t enough room on the taskbar to display a button for each open window, Windows Vista groups similar types of windows under one button. You can identify a window by its name on the title bar at the top of the window. To organize your desktop, you must sometimes change the size of a window or move it to a different location. Each window is surrounded by a border that you can use to move or resize the window. Each window has resize buttons in the upper-right corner.
All windows contain the same sizing and close buttons:
Maximize button. Click to make a window fill the entire screen.
Restore Down button. Click to reduce a maximized window.
Minimize button. Click to shrink a window to a taskbar button.
Close button. Click to close the window.
