Windows Wallpapers Repository

[renone]

Hello everybody,
maybe I will sound like a noob, but using search here in the forum didn't bring up anything.

I just wanted to know if exists a repository of every windows wallpaper ever seen, including the ones available in retail versions or development versions (Alphas, Betas, RCs, etc.).

Thanks in advance, any help will be appreciated

Many Thanks DragonExagon, for sure this site is great.

But it misses backgrounds from the before-7 era (Win Xp) and the one from Beta versions.
