Windows NT 3.1 build 297

Windows NT 3.1 build 297.1 is the official July 1992 preliminary release of Windows NT 3.1, distributed to developers for evaluation. KenOath first claimed to have this build, then it was leaked in April 2011, along with the October 1991 and December 1991 builds.

It can now properly shut down and introduces the safe to shutdown dialog that would be kept until early Windows 2000 builds. Keyboard also now works for PCem. It has an option to format the system partition with NTFS during setup, but it doesn't work since it's still just a placeholder.

It is also the first build to include the NTVDM (NT virtual DOS machine).
