Program Manager is the shell of Windows 3.x and Windows NT 3.x operating systems. This shell exposed a task-oriented graphical user interface (GUI), consisting of icons (shortcuts for programs) arranged into program groups. It replaced MS-DOS Executive, a file manager, as the default Windows shell.
OS/2 2.0 and later included the Program Manager as part of its Win-OS/2 compatibility layer. Win-OS/2, including the Program Manager, are still included in later derivatives of OS/2 such as ArcaOS.
