Windows 1.0 runs a shell program known as MS-DOS Executive. Other supplied programs are Calculator, Calendar, Cardfile, Clipboard viewer, Clock, Control Panel, Notepad, Paint, Reversi, Terminal, and Write.
Windows 1.0 does not allow overlapping windows. Instead all windows are tiled. Only dialog boxes can appear over other windows.
Windows 1.0 executables, while having the same .exe extension and initial file header as MS-DOS programs, do not contain the so-called MS-DOS stub which prints the “This program requires Microsoft Windows” message and exits when the program is run outside of Windows. Instead, the file header was formatted in such a way as to make DOS reject the executable with a “program too large to fit in memory” error message.
