Update: I’ve been kindly informed by Josh from WindowsConnected.com that these wallpapers are very old. In fact, so old that it makes the 4th generation iPod look new. Actually they are only dated back to 1st of June, 2006. But since I’ve removed the branding, some of you might still find it interesting.
These wallpapers come from the Microsoft Partners website for Windows Vista. They’re a little different to most of the Auroras I’ve seen, but Auroras all look the same these days. The only negative thing is that they come with the Vista orb, “see the difference” and “partners” branding. I’ve removed the “partners” branding for two of the highest resolution wallpapers (normal & widescreen) which you can scale down if you prefer not to have branding.
All three variations are bundled in the ZIP file for your desired resolution:
