Windows Longhorn build 4031 (main)

Windows Longhorn build 4031 (main) is a Milestone 5 build of Windows Longhorn. 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 later released in the ninth set of his 33 Longhorn/Vista builds on 2020-02-01, alongside the main lab compile of 4085, the x86 version of 4083, the Lab06_n compile of this build, its Lab07 Server counterpart and build 5520. This build is currently the latest leaked Milestone 5 build and therefore still uses the wallpaper from previous Milestone 5 builds.

Setup
Setup is practically similar to previous Milestone 5 builds.
