Windows Longhorn build 4030 (Lab06 n.030630-1724)

Windows Longhorn build 4030 (with a build tag of 4030.Lab06_N.030630-1724) is one of the first Milestone 6 builds of Windows Longhorn. It is fairly similar to the earlier build 4029, however it features the new Milestone 6 background. It is one of the earliest builds to feature "3D View", however it is unusable and doesn't draw icons properly. This build needs modification to enable Aero. This build leaked on 2020-01-23
