Smart App Control is a Windows 11 application-control feature that uses Microsoft’s app intelligence and Windows code integrity capabilities to help block untrusted or suspicious applications. It assesses software before it runs, adding a layer of defense against potentially harmful code.
In real-world defenses, Smart App Control can help prevent risky applications from executing on a device. Administrators should verify that the feature is enabled and functioning as intended, especially after system updates or configuration changes. A problem re-enabling the feature is distinct from a failure of enforcement on devices where it is already active.
