REAgentC comes\r\nwith Windows, and you can run the REAgentC command on an offline Windows image or on a running Windows\r\noperating system.\r\nNote\r\nIf you're using Windows PE 2.X, 3.X, or 4.X to configure recovery on an offline installation, you must use the\r\nWinrecfg.exe file from the Recovery folder of the Windows Assessment and Deployment Kit (Windows ADK).\r\nWinrecfg.exe supports only the offline operations that REAgentC.exe supports.\r\nREAgentC syntax\r\nreagentc.exe \u003ccommand\u003e \u003carguments\u003e\r\n/setreimage\r\nSets the location of a Windows RE boot image.\r\nSupports both online and offline operations.\r\n/setreimage syntax\r\n/setreimage /path \u003cpath_to_Windows_RE_image\u003e [/target \u003cpath_to_offline_image\u003e]\r\n/setreimage usage\r\n/path supports UNC paths to locations on the local disk. For example:\r\nReagentc /setreimage /path S:\\Recovery\\WindowsRE`\r\n/target Specifies the location of the Windows image when you apply the setting offline.

To override the default behavior and enable Windows RE from audit mode, specify the /auditmode\r\noption. For example:\r\nReagentc /enable /auditmode\r\nIf you generalize the image after you use the /enable option in audit mode, Windows RE is disabled until\r\nyou use the /enable option again or until after the specialize configuration pass runs.\r\n/osguid {\u003cbcd_guid\u003e} allows you to enable your custom Windows RE boot image from Windows PE. It\r\ncan only be used after bcdboot.exe has been run. \u003cbcd_guid\u003e is the Boot Configuration Data (BCD)\r\nidentifier of the target Windows installation, obtained by running bcdedit -enum -v .\r\nReagentc /enable /osguid {00000000-0000-0000-0000-000000000000}\r\n/disable\r\nDisables any active Windows RE image that is mapped to the online image.\r\nSupports only online operations.\r\n/disable usage\r\nReagentc /disable\r\n/boottore\r\nhttps://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/reagentc-command-line-options?view=windows-11\r\nPage 2 of 4\n\nSpecifies that Windows RE starts automatically the next time the system starts.\r\nSupports only online operations.\r\n/boottore usage\r\nReagentc /boottore\r\n/setosimage\r\nThis setting isn't used in Windows 10 or later\r\nRegisters the location of a push-button reset image in an online or offline image.

For\r\nexample:\r\nReagentc /setosimage /path R:\\RecoveryImage /index 1\r\nThe /target option specifies the location of the offline Windows image. For example:\r\nReagentc /setosimage /path R:\\RecoveryImage /index 1 /target W:\\Windows\r\n/info\r\nDisplays the current status of Windows RE and any available recovery image on an online or offline image.\r\nSupports both online and offline operations.\r\n/info syntax\r\n/info [/target \u003cpath_to_offline_image\u003e]\r\n/info usage\r\nhttps://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/reagentc-command-line-options?view=windows-11\r\nPage 3 of 4\n\n/info on its own returns the status of the online operating system:\r\nReagentc /info\r\nThe /target option obtains configuration information about an offline image.
