Examples

The following example shows how to register for the SmartAppControlPolicy.Changed event and handle the event when it's raised.

using Windows.System.Profile;

public class SmartAppControlPolicySample: IDisposable
{
    public SmartAppControlPolicySample()
    {
        SmartAppControlPolicy.Changed += OnSmartAppControlPolicyChanged;
        OnSmartAppControlPolicyChanged();
    }

    ~SmartAppControlPolicySample()
    {
        SmartAppControlPolicy.Changed -= OnSmartAppControlPolicyChanged;
    }

    public void HandleSmartAppControlPolicyChange()
    {
        //
        // Change related UI Elements
        //
        ChangeUIForSmartAppControl(SmartAppControlPolicy.IsEnabled);
    }

    void OnSmartAppControlPolicyChanged(object args)
    {
        //
        // Smart App Control Policy state changed.
        //
        HandleSmartAppControlPolicyChange();

        //
        // Manage detection settings.
        //
        if (!SmartAppControlPolicy.IsEnabled)
        {
            //
            // Set AV in full scanning mode.
            //
            SetMalwareDetectionBehavior(MalwareDetectionBehavior.FullDetectionMode);
        }
        else
        {
            //
            // Set AV in light weight scanning mode.
            //
            SetMalwareDetectionBehavior(MalwareDetectionBehavior.LightweightDetectionMode);
        }
    }
}

Remarks

Smart App Control is a new security feature in Windows 11, which improves consumer PC security by blocking apps that are malicious or untrusted. It is implemented as a Microsoft Defender Application Control (MDAC) policy, similar to Windows in S mode.

Apps and services may want to query the Smart App Control mode on a given system, or register for a notification when the state changes. This can be done with the SmartAppControlPolicy APIs.

Properties

IsEnabled

Indicates whether Smart App Control is enabled.

Events
