WindowFX is a program that takes advantage of many of the hidden visual APIs in Windows. Depending on which version of Windows you are running, it can do some amazing things ranging from adding real alpha blended shadows under windows to having semi-transparent menus. It also provides users who run at high resolution the ability to set their window maximization size. It introduces skinning to the desktop background. Now users can have animated wallpapers that use little CPU. A library of desktop skins is available from which users can have their desktop wallpaper provide news, animation, and more without the normal CPU hit one would get from Active Desktop.
