Windows NT 4.0/4.0.1130.1

Windows NT 4.0 build 1130.1 is the earliest leaked build of Windows NT 4.0. It includes Explorer interface and is similar to Windows NT 4.0 build 1141.1. The Workstation SKU was found on Fate 008 and was eventually leaked. Because this is early in the development, it still contains Windows NT 3.x apps and program groups, which makes it is very similar to the Shell Update Release of Windows NT 3.51.
