 #### Important information about removing Exploit Guard settings from a device
 
 When you deploy an Exploit Guard policy using Configuration Manager, the settings remain on the client even if you later remove the deployment. If the deployment is removed, the client logs `Delete` not supported in the `ExploitGuardHandler.log` file.
