Windows NT 3.5 build 782

Windows NT 3.5 build 782.1 is the official Release Candidate 2 build of Windows NT 3.5. While this build has been available in binary form for many years, the source code for this build was leaked on 15 May 2020. The leaked code has been shown to be compilable and produce many binaries necessary for a working system. However, the leaked source code lacks source files for certain components such as encryption, instead supplying pre-compiled files. These source files were likely left out for security reasons. It is also the first known build to include the  launch parameter in   to install from an MS-DOS prompt.
