This style can be found in the
Windows Embedded Standard CTP Refresh. It's called "
Embedded" and, along with the wallpaper, gets copied into the image if the
Windows XP UI component is added. As it's digitally signed it works with any XP/Server 2003 install. The archive I uploaded below contains the Embedded folder and the Embedded.theme to be copied to %systemroot%\resources\themes and the wallpaper in its original format and size.
