Windows NT 3.5 build 683

Windows NT 3.5 build 683 is the official beta 2 build of Windows NT 3.5. The Workstation edition was shared by a warez group in 1994, but the floppy disks were mistakenly dumped in 1.44MB images instead of DMF (1.68MB), resulting in unrecoverable data loss. This means most of the disk images are broken and the Workstation SKU of this build is unusable. The floppy version of the Server edition on this build was included on the Chinese warez CD set "立人软件大补贴", of which all but one CD was uploaded by 老光盘交流群 member 独鹤与飞 on 24 March 2019, reuploaded to the Chinese website BetaWorld on 19 October 2019, and reuploaded to the Internet Archive on 2 September 2022. The ISO image of the Server SKU of this build was found and shared to BetaArchive on 27 September 2020.

This build is also mentioned in the file  from Windows NT 3.51 build 854.1.
