October 1991 pre-release of Windows NT 3.1 is the earliest leaked Windows NT build. It was originally was compiled for the COMDEX Trade Show in October 1991. Interestingly, this build does not have a build number. WINVER reports it as Version VERSION. People speculate that this build was rushed to completion so it was ready in time for the show, which would explain the lack of a build number and MIPS port. The October 1991 pre-release is also one of few Windows NT builds before Longhorn build 4001 to have a fully graphical setup, a feature which later returned in 4001 with the WIM-based setup.
