Editing Program Manager (section)

==Overview==
Program Manager descends from ''Desktop Manager'' (also known as [[Presentation Manager]]), the shell for [[OS/2]] 1.2.<ref>[http://toastytech.com/guis/os212.html OS/2 1.2]</ref> Unlike Desktop Manager, which presents its program groups in a simple list, and opens each group in a separate window, Program Manager opens program groups in child windows using the new [[multiple document interface]] in Windows 3.x. The icons used to represent Program Manager itself, program groups, and DOS applications in [[Windows 3.0]] are carried over from OS/2 1.2. [[Windows 3.1]] uses updated versions of these icons.

When executables were dropped into Program Manager from [[File Manager (Windows)|File Manager]], Program Manager automatically used the executable's default icon embedded as data inside the .EXE file.  Additionally, the Windows Setup program, which populated Program Manager with the standard icons of a fresh install, could also be used to add new icons in bulk after installation. Using SETUP /P from the [[command line]], a standard layout could be installed on many machines in an enterprise using a single SETUP.INF configuration file.<ref name="Livingston-1993" />{{rp|38}}

Beginning with Windows 3.1, Program Manager contained a StartUp group. Programs and files placed into that group would be loaded when Windows starts.

Holding down the shift key while selecting File then Exit Windows will save the current configuration of Program Manager to PROGMAN.INI, including the position of all program group icons, assuming that auto-arrange has been disabled.  This allowed Microsoft testers to try many different configurations, but the feature remained in the shipped version.<ref name="Livingston-1993">{{cite book|last=Livingston|first=Brian|year=1993|title=More Windows 3.1 Secrets|publisher=UDG Books Worldwide, Inc.|location=San Matao, CA|isbn=1-56884-019-5|url-access=registration|url=https://archive.org/details/morewindows31sec0000livi}}</ref>{{rp|33}}

In later versions of [[Microsoft Windows]], starting with [[Windows 95]] and [[Windows NT 4.0]], Program Manager was replaced by [[Windows Shell]]. The [[Start menu]], the [[Windows_shell#Desktop|Desktop]], and the [[Taskbar]] took over program organization and launching duties.

Program Manager was still included in later versions of Windows, and could be accessed by executing <code>PROGMAN.EXE</code> from the command line or ''Run'' dialog. It could be used as the default shell by specifying the ''Shell'' value in [[Windows Registry]] at either <code>HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon</code> (per machine) or <code>HKCU\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon</code> (per user).

Microsoft replaced Program Manager in [[Windows XP Service Pack 2]] with a [[Method stub|compatibility stub]] that simply redirects to Windows Explorer. In [[Windows Vista]] and later, <code>PROGMAN.EXE</code> was permanently removed from the operating system.
