Windows Longhorn build 4040

Windows "Longhorn" build 4040 is a Milestone 6 build of Windows Longhorn and was one of the last for said milestone. Grabberslasher first described this build on his UX.Unleaked blog on 2008-06-06. On 2020-01-31, he leaked this build to BetaArchive. Some screenshots found on the Internet were later revealed to be 4039 with a modified build tag. This build is one of the last builds to include the Plex theme, together with the main compile of 4042.

 * 3D spinning icons - which were first seen in 4029.main.030619-0000.

 * Plex - the version from the leaked build 4033.main.030717-1555.
