CerHost is a lightweight, proprietary utility from Microsoft that allows you to view and control the desktop of a Windows CE-based device from your host PC over an Ethernet connection.

On some embedded systems, if CerHost is disabled, you may need to clear specific registry files (like CeRemoteDisplay_Disable.reg ) and reboot to restore access.

Launch CerHost.exe . You can find this tool in various SDKs or download it from industrial hardware providers like Beckhoff or ICP DAS .
