XPize is a GUI enhancer for Windows XP and above. It replaces most of the non-XP icons, avis and bmps that Microsoft has always overlooked. The installer simply automates the process of replacing resources in critical system files, making your XP's look better. It also includes some extras and a reloader, which you can use after visiting Windows Update.
