Windows Longhorn build 4040

Windows "Longhorn" build 4040 is an Milestone 6 build of Windows Longhorn and was one of the last for that milestone. It was first described by Grabberslasher on his UX.Unleaked blog on 2008-06-06. Some screenshots found on the Internet were later revealed to be 4039 with a modified build tag. This build leaked on 2020-01-23. This build is one of the last builds to include the Plex theme, together with the main compile of 4042.

Features

 * Aero Glass (frame only) barely works, having problems such as not redrawing the window contents unless resizing the window. Both variants of Aero Glass are included - transparent and opaque.
 * "3D View" option is available in the shell view menu, enabling a MIL-rendered file view.
 * 3D spinning icons - which were first seen in 4029.main.030619-0000.
 * Phodeo and Carousel.
 * Plex - the version from the leaked build 4033.main.030717-1555.
