I’ve been trying out various beta / rc builds of Windows 7 during the past few months, and often new builds come with a new set of wallpapers. Finally got around organizing them a bit and placing them in my photo gallery.
The wallpaper gallery is available here (to get the original version select “Download Photo 1920×1200 from the dropdown), or to grab them all all together:
– Windows 7 Wallpaper Collection b7000
– Windows 7 Wallpaper Collection b7048
