Windows NT parses the AUTOEXEC.BAT file during startup by default, which results in the appending of the path statement in the AUTOEXEC.BAT file to the system path created by Windows NT. You can modify the system path and evironment variable at Control Panel/System/EnvironmentTab. You can configure parsing of the AUTOEXEC.BAT file at:
1 = autoexec.bat is parsed
0 = autoexec.bat is not parsed
This has no effect on the parsing of AUTOEXEC.NT or CONFIG.NT by the MS-DOS or 16-bit Windows environments (VDMs).
