Windows 7 build 7066

Windows 7 build 7066 is an unleaked build of Windows 7. Two pictures of this build were found on the websites of the artists of two of the wallpapers introduced in build 7057. The first, being from Adhemas Batista, the illustrator of img28, was proven to be only a concept, due to the watermark not being placed correctly, while the other, from Osmand Nosse, the illustrator of img21, is most likely real.
