Windows Longhorn build 4042 (main)

Windows Longhorn build 4042 (main) is a build of Windows Longhorn. This build was compiled four days before the Lab06_n compile, and as such, is technically a Milestone 6 build. Prior to its leak, UX.Unleaked had a post with three images from this build. Later on 23 January 2020, this build was listed on a thread by the blog's founder Grabberslasher to be released to the BetaArchive FTP, and was released in the twelfth and final set of his 33 Longhorn/Vista builds on 4 February 2020 along with build 4082, build 4087 and build 5492.

Setup
Setup is mostly similar to previous builds of Longhorn.

Bugs

 * If you want to launch setup from Windows, you must ensure that the setup files are in a folder without a space, or else setup will fail to launch with the errors "An unknown command line option main\sources was specified" followed by "The required file install.wim is not found on the source ".
