/auditmode [Windows 11], by default Windows will not perform any actions when Windows is in audit mode.
To over-ride this default and enable WindowsRE from audit mode specify /auditmode
e.g. /enable /auditmode
If you generalise the image after using /enable in audit mode WindowsRE is disabled
until you use enable again or until after the specialize configuration pass runs.
/configfile xml_name Specifies the path to the XML configuration file for the boot menu entry.
/logpath file_path The path of log file.
If this argument is not specified, the default path is Windows\Logs\Reagent\Reagent.log.
/osguid bcd_guid Specifies the Boot Configuration Data (BCD) identifier of the target
Windows installation. The identifier can be determined by running "bcdedit -enum -v".
/path dir_path_to_win_RE_image The directory that contains the custom Windows RE image (winre.wim).
/target dir_path_to_offline_image The Windows installation.
If this argument is not specified, the running Operating System is used.
