Audit Windows machines on which Windows Defender Exploit Guard is not enabled

Policy DisplayName Audit Windows machines on which Windows Defender Exploit Guard is not enabled
Policy Id bed48b13-6647-468e-aa2f-1af1d3f4dd40
Policy Category Guest Configuration
Policy Description Requires that prerequisites are deployed to the policy assignment scope. For details, visit https://aka.ms/gcpol. Machines are non-compliant if the PowerShell command Get-MPPreference returns configuration details that does not match expected values. Windows Defender Exploit Guard helps protect against malware that uses exploits to infect devices and spread. Exploit Guard protection consists of a number of mitigations that can be applied to either the operating system or individual apps.
