Windows Longhorn build 4040

Windows "Longhorn" build 4040, with a build tag of 4040.Lab04_N.030828-1910 is an unleaked Milestone 6 "Longhorn" build and was one of the last for that milestone. It was first described by Grabberslasher on his UX.Unleaked blog on 2008-06-06.

This Build 4040 is the last known build to include the Plex theme. (While build 4042_main, which was compiled later, does include the theme by default, it is not known to exist. Screenshots found on the Internet were later revealed to have had the buildtag edited; the build was in fact 4039.
