Windows (95, 98, ME, 2000, XP) To change your desktop wallpaper in Windows, simply right-click on the desktop, and choose Properties. On the Desktop (or Background) tab, make your selection and preview it in the little monitor. You can choose whether your selection looks better centered, tiled, or stretched by selecting one of those choices in the box labeled Position (or Display). If a pattern you want is not shown as a choice, click the Browse button to find it.
