Windows Longhorn build 4074 is an official WinHEC 2004 preview build, which leaked in 2004-05. This build is a Milestone 7 build of Longhorn and the most famous pre-reset build of Longhorn as it was distributed publicly.
This build is the first to default with the Segoe UI font that would be used by default in later Windows operating systems. Many icons from Windows XP were replaced with new, high-resolution versions, as with build 4066. While the Slate theme is still present, it also contains the new Jade theme that is also present in build 4066. The default wallpaper has also been changed to "Leaves". The Jade theme also enables native Aero transparency, which has not been seen since build 4042.
