Release of the month Windows NT 3.1 1991-10 build October 1991 release of Windows NT 3.1 was compiled for the COMDEX Trade Show in 1991-10. Interestingly, this build does not have a build number, unlike both earlier and later builds. Instead, Winver displays "Version VERSION" in place of the actual version number. It is speculated this build was rushed to completion so it was ready in time for the show, which could be the reason for the lack of a build number and MIPS port. It is also one of few Windows NT builds before Longhorn to have a fully graphical setup, a feature which has not returned until Longhorn build 4001 with its WIM-based setup.
