Windows NT October 1991 is the oldest known build of Windows NT. It was released at COMDEX '91 and was rushed to completion and was not released for the MIPS platform.
Several screenshots were shown by BetaArchive member linuxlove and a pre-installed VHD (For QEMU and VMware) was leaked containing the SDK and Free files of the OS.
In late 2011, the full CD was released on BetaArchive.
