Style XP Beta can import, select, and manage Themes, Visual Styles, and Wallpaper. Future versions may support sounds, cursors, screensavers, logon UIs, and packages of all the above. Style XP is not a skinning engine. It uses Microsoft's built-in visual style engine, but enhances it by providing many useful tools.
