Winter

Winter, originally known as Snow and Frost on Trees in Forest, is a sample picture included in Windows XP, licensed from Corbis. It was taken by Mark Karrass, who also took Ascent, Blue hills and Longhorn's Aero Woods. It depicts a snowy forest at night, although it is unknown which forest it was taken at. It is no longer available on Getty Images and other stock photo sites with the exception of Photononstop. A high res version is available from Corbis CD Nature and Landscapes, which also has Aero Woods at a high resolution. It has also been unofficially made available on Depositphotos.

It would later be used as a wallpaper in a Longhorn UI demo circa 2002; a screenshot of said demo can be found here.
