No matter how many windows you have open, you can always minimize all of them at once by clicking the Show Desktop button in the Quick Launch part of the taskbar in Windows XP. If you change your mind and don’t want to use the desktop, you can click the Show Desktop button again to restore all of your windows.

Note  If you don’t see the Show Desktop button, right–click an empty part of the taskbar, point to Toolbars, and make sure Quick Launch is checked. If itÂ’s not, then click it.
