Sysedit (SYSEDIT.EXE) is a specialized text/ASCII editor for core Microsoft Windows configuration files (such as PROTOCOL.INI, WIN.INI, SYSTEM.INI, CONFIG.SYS, and AUTOEXEC.BAT). This executable is installed in the Windows system directory: %windir%\SYSTEM (Windows 3.x and 9x editions) or %windir%\SYSTEM32 (Windows NTx editions). Sysedit was bundled with and automatically installed by every version of Windows from Windows 3.0 up to Windows 98 SE. Support was discontinued with Windows Me.
