- An assorted mix of wallpapers from Longhorn builds, UI demos (both Longhorn and Blackcomb), and Vista Beta builds.
- Most of these come from Getty Images, except Aero Woods and Winter. Both of these are no longer on Getty Images, though some guy called "moooon" uploaded several pictures they didn't even take to Depositphotos, including these. Someone I knew bought both of those for me. Frog was also taken down, though I managed to find a HQ version by reverse searching. Unlike the Longhorn version it has no blur.
- The version of Excalibur featured here is the slightly differently colored Getty version, as the Corbis version and David Muench's Corbis contract were not transferred to Getty. On Getty it has been flipped, though I re-flipped it to match the original.
- I am not 100% sure about the origins of Grass, close-up and View to Ben Lomond. The former is allegedly in the "Seasons Theme" for Vista build 5308, though I've not found anything about that. The latter seems to be associated with Longhorn, though I can't find which demo it was used in. Both are from Getty though, which hints they're most likely official.
- I'm not sure if Dew Drop was used for Longhorn or not. It also appears in Mac OS X, though it appears in dejco's Longhorn wallpaper pack so eh, I included it here. 
- Twilight at Lake Powell, Arizona has been flipped to match the Longhorn demo version. 
- Some of the filenames are taken from dejco's Longhorn wallpaper pack or the OS Mockup Kit. The build wallpapers are given more distinct names than "Bliss". Demo wallpapers that aren't in those packs are named after their corresponding pictures on Getty. 
- Excalibur, Gold Petals and Winter are reused from Plus! 98, 2000 and XP respectively. 

Many of these are not present due to:
- some of them being taken down from Getty Images, and having no HQ version available.
- some of them most likely being taken by Microsoft employees, so no HQ version is available.
- some of them such as the Longhorn 4074 wallpaper and grass wallpaper originally being vertical, so they are not wide enough since ZeonDownloader only downloads at 2048px max without upscaling.
- some of them not even being known yet (Longhorn demos used an insane amount of wallpapers in total), or the demo screenshots are too blurry to find their origin.
