Windows 3.1 build 005 is an unconfirmed build of Windows 3.1. If real, it would be the earliest known build of Windows 3.1. A WINFILE.EXE file that reports the build number and corresponding SHELL.DLL are included in a warez package marked as "MSWin3 beta File Manager from v3.1", which was later found and released on 25 June 2024.
