Windows NT 4.0 build 1130

Windows NT 4.0 build 1130.1 is the earliest available build of Windows NT 4.0. This build comes with the Windows Explorer interface. The Workstation edition was listed on the Fate 008 warez CD, but was found in another warez source and shared on OSBetaArchive on 9 December 2015.

Being very early in development, it still contains many Windows NT 3.x apps and program groups on the Start menu, and is very similar to the Shell Technology Previews of Windows NT 3.51.
