Windows Longhorn build 4050 (idx02)

Windows Longhorn build 4050 (idx02) is a Milestone 7 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 fifth set of his 33 Longhorn/Vista builds on 2020-01-28, alongside build 4085 (Lab07_N). Currently, the only version of this build is the Check/Debug build and is the second leaked Home Edition pre-reset build of Longhorn. It is possible that there is a regular ISO of the build but if there is, it remains unleaked.

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. As it is currently only available as a Check/Debug build this is necessary.
