Windows Longhorn build 4029 (main)

Windows "Longhorn" 4029 (with a build tag of 4029.main.030619-0000) is a Milestone 5 build of the Microsoft Windows "Longhorn" operating system.

This late-Milestone 5 build was compiled on 2003-06-19 and has the dubious distinction of Pig Latin in the build string! This was a test of automatic data entry that would become commonplace in later builds and eventually, Vista.
