Windows NT 3.1 build 340
|Build of Windows NT 3.1|
Windows NT 3.1 build 340 is the 1992-10 pre-release build of Windows NT 3.1, available in both standard and server editions. The latter was leaked on 2017-11-03 by The Distractor on BetaArchive. It is the earliest leaked build of the server version of Windows NT, at the time still called "LAN Manager for Windows NT".
This build is often mislabeled either as build 319 or 328, which are actually file versions of its kernel files (
NTKRNLMP.EXE). NTFS now works in this build.
