A free Winter Fun Pack is now available for Windows XP through the Windows Genuine Advantage Program. It includes some desktop pictures, Windows Media Player visualizations and skins, and a Media Center Plugin.

Just to hopefully avoid any conspiracy theories about the genuine advantage program - the goal isn't to find users pirating Windows, but to find people illegally distributing Windows. If a user finds they don't have a genuine version, they can get a genuine version for free (I'm too lazy to look up a link to the recent stories on this).
