Windows 1.0 Fall COMDEX build

The first time Windows was shown to the public was at Fall COMDEX on 10/11/1983, although an earlier build was shown in BYTE Magazine the following month. Both builds remain unleaked. This build was compiled on November 1, 1983, 1 year before DR5. Video of Fall COMDEX 1983 (Windows 1.0 demo shown about 7 minutes in)
