If you open more than one program or document, your desktop can quickly become cluttered with windows. Keeping track of which windows you have open isn't always easy, because some windows might partially or completely cover others.
Using the taskbar. The taskbar provides a way to organize all of your windows. Each window has a corresponding button on the taskbar. To switch to another window, just click its taskbar button. The window appears in front of all other windows, becoming the active window—the one you're currently working in.
To easily identify a window, point to its taskbar button. A small picture called a thumbnail appears that shows you a miniature version of the window. This preview is especially useful if you can't identify a window by its title alone.
If the taskbar becomes too crowded with buttons, then the buttons for the same program become grouped into a single button, as shown in the picture below. Click the button to see a menu of the items in the group, then select an item to make it the active window. For more information about taskbar buttons, see The taskbar (overview).
Using ALT+TAB. You can switch to the previous window by pressing ALT+TAB, or cycle through all open windows and the desktop by holding down ALT and repeatedly pressing TAB. Release ALT to show the selected window.
Using Windows Flip 3D.
Windows Flip 3D arranges your windows in a three-dimensional stack that you can quickly flip through. To use Flip 3D:
Hold down the Windows
and press TAB to open Flip 3D.
While holding down the Windows logo key, press TAB repeatedly or rotate the mouse wheel to cycle through open windows. You can also press RIGHT ARROW or DOWN ARROW to cycle forward one window, or press LEFT ARROW or UP ARROW to cycle backward one window.
Release the Windows logo key to display the frontmost window in the stack. Or, click any part of any window in the stack to display that window.
Flip 3D and taskbar window previews won't work unless your computer is running Windows Aero, the premium visual experience of Windows Vista. Aero is not available in Windows Vista Starter or Windows Vista Home Basic. For more information, see How do I get Windows Aero?
You can also open Flip 3D by clicking the Switch between windows
on the taskbar. Then click a window in the stack to display that window, or click outside the stack to close Flip 3D without switching windows.
