Windows Longhorn build 4050 (idx02)

Windows Longhorn build 4050 (idx02) is a Milestone 7 build of Windows Longhorn. On 23 January 2020, 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 fifth set of his 33 Longhorn/Vista builds on 28 January 2020 as a checked/debug build alongside build 4085 (Lab07_N). It is the second leaked Home Edition pre-reset build of Longhorn.

Setup
Setup is mostly the same as the previous build of Windows Longhorn.

Changes

 * The login screen has been revamped once again, now featuring just a solid-black background.

Installation
This build requires either a debugger or replacing drivers with ones from the non-Check/Debug versions from build 4051 due to the large amount of assert errors that prevents setup from installing properly.
