Windows NT 3.1 build 297.1
|Build of Windows NT 3.1|
Windows NT 3.1 build 297.1 is the 1992-07 preliminary release of Windows NT 3.1, distributed to developers for evaluation. KenOath first claimed to have this build, then it was leaked in 2011-04, along with the 1991-10 and 1991-12 builds.
This build can now properly shut down and introduces the safe to shutdown dialog that would be kept until early Windows NT 5.0 betas. Keyboard also now works for PCem. This build has an option to format the system partition with NTFS during setup, but it doesn't work since it's still just a placeholder.
