Windows Longhorn build 4042 (main)

Windows Longhorn build 4042 (main) is a Milestone 7 build of the Windows Longhorn operating system. It was compiled four days before the Lab06_n compile, and as such, was technically a Milestone 6 build. This build still uses the old boot screen and wallpaper from previous Milestone 6 builds and is less stable and usable than the Lab06_n complie. This build still uses Pig Latin in its build string. As with 4040, both opaque and transparent Aero glass options are available. On 2020-01-23, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be released to the BetaArchive FTP, and was released in the twelfth and final set of 33 other Longhorn builds on 2020-02-04 along with build 4082, build 4087 and build 5492.
