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 build tag edited; the build was in fact 4039.
