AeroXperience found an unusual Windows Vista Build while surfing on the Windows Hardware Developer Central website

While surfing around on the internet, we located something quite unusual. Buried within several technical videos was a Windows Vista build of 6429.fbl_multimedia_media.070514-1730. We won't bother speculating as to what this build represents, but word is spreading that this could be an early developmental build of Windows "7" (or a dogfood SP2 build). A UAC prompt within the Local Training demo shows the build as being a WEX build.
