MSConfig, or Microsoft System Configuration Utility, (or simply System Configuration in Windows Vista) is a utility to troubleshoot the Windows startup process. It is bundled with all Microsoft Windows operating systems since Windows 98 except Windows 2000. Windows 95 and Windows 2000 users can download the utility as well, although it was not designed for them. MSConfig modifies which programs run at startup, edits certain configuration files, and simplifies controls over Windows services. As part of the base Windows install, MSConfig can be accessed by running 'msconfig' on any system on which the user has administrator access.
Prior to Windows Vista, files that can be edited through MSConfig include AUTOEXEC.BAT, CONFIG.SYS, WIN.INI, SYSTEM.INI on Windows 9x systems, and WIN.INI, SYSTEM.INI and BOOT.INI on Windows NT systems prior to Windows Vista. The chief benefit to using MSConfig to edit these files is that it provides a simplified GUI to manipulate sections of those files and the Windows registry tree pertaining to the Windows boot sequence. Using MSConfig, Windows can also be configured to perform a diagnostic startup (load a minimum set of drivers, programs and services).
