Hello Everyone, here is another post from Configuration Profiles for you all. We will learn how to Enable the Detect Potentially Unwanted Applications using Intune. Here also, we will make use of Configuration Profiles from Intune to achieve this task.
You may risk infecting your network with malware due to potentially unwanted applications, which makes identifying malware attacks more difficult, and uses IT resources to remove the applications from your network. In order to prevent their installation, they should be blocked.
As a result of these applications, your network may become infected with malware more easily, making malware infections harder to identify among the noise, and waste helpdesk, IT, and user time cleaning up the applications. Detect Potentially Unwanted Applications (PUA) policy from MS Defender has already been deprecated.
Potentially Unwanted Applications (PUA) are sneaky unwelcome application bundlers that can deliver adware or malware. This policy setting controls the detection and action of PUAs. Windows Defender protects against Potentially Unwanted Applications if this setting is enabled.
In the event that this setting is disabled or not configured, Potentially Unwanted Applications protection will not be enabled. With Windows 10 v1809 and Windows Server 2019, this functionality is instead configured through Group Policy settings: Computer Configuration\Administrative Templates\Windows Components\Windows Defender Antivirus, Configure detection for potentially unwanted applications.

Intune MDM Event Log
Intune event ID 813 or 814 indicates that a string policy has been applied to Windows 10 or 11 devices. In addition, you can view the exact value of the Policy that is being applied to those devices.
You can check the Event log path to confirm this – Applications and Services Logs – Microsoft – Windows – Devicemanagement-Enterprise-Diagnostics-Provider – Admin.
The log states the following – MDM PolicyManager: Set policy string, Policy: (TurnOnWindowsDefenderProtectionAgainstPotentiallyUnwantedApplications),
