Enabling Smart App Control (SAC) on Windows 11 provides an added layer of protection against malicious software and untrusted apps. This guide will walk you through the process of configuring this essential security feature.
Understanding Smart App Control
Smart App Control is a robust security feature built into Windows Security, specifically designed to restrict the execution of applications to those that are verified as trustworthy. It ensures that your device only runs applications with valid signatures, thus significantly reducing the risk of malicious software running on your system.
This feature is exclusive to Windows 11 versions 22H2, 23H2, 24H2, and any future releases, as Smart App Control is not supported in older versions, including Windows 10.
How Smart App Control Functions
Smart App Control is most effective when installed on a device with a pristine version of Windows 11. During the initial phase after installation, it operates in “Evaluation” mode, assessing the applications you use. This mode allows SAC to gather data on how apps influence your system and user experience. If the evaluation indicates that SAC can safely operate without any hindrances, it transitions into active protection mode. If issues arise, it remains inactive to avoid disruptions.
Disabling Smart App Control
After the evaluation phase concludes, Smart App Control is programmed to enable itself automatically. However, once activated, you cannot simply disable it. If an application is blocked, you will be unable to reinstate it without first disabling SAC, which requires a complete system reinstallation.
Should you decide to disable the feature, your only options are either performing a clean installation of Windows or resetting your system while opting to keep your files.
In this guide, I will delineate the steps necessary to activate the Smart App Control feature on your Windows 11 device, along with recommendations for enhancing your overall system security.
How to Enable Smart App Control on Windows 11
Follow the steps below to effectively enable Smart App Control on your Windows 11 system:
-
First, launch the Windows Security application.
-
Next, navigate to the App & browser control section.
-
Then, click on Smart App Control settings.
-
Select the Evaluation option.
Quick Note: If the setting is marked as “Off, ” it may be due to your device not featuring a clean installation or the evaluation mode finding that the device cannot support the feature.
Upon completing these steps, Smart App Control will operate discreetly in the background without blocking any applications. During this evaluation stage, the system will monitor how the apps perform to ascertain whether it can run SAC without any impacts. If Smart App Control is able to operate smoothly, it will automatically activate; otherwise, it will remain off.
It is crucial to understand that enabling this feature may lead to Smart App Control blocking some trusted applications. In such instances, access to those apps will be restricted until SAC is disabled, as there is no built-in functionality to unblock specific applications.

If Smart App Control mistakenly blocks a trusted application, you will need to disable the feature entirely, which requires a clean installation of Windows. Ensure to back up your important files before proceeding.
2. How long does Smart App Control stay in evaluation mode?
The length of time Smart App Control remains in evaluation mode can vary based on the applications you use. It monitors your experience for a period to decide if it can function without issues; if successful, it will automatically activate.
3. Can I customize the performance of Smart App Control?
Currently, Smart App Control does not allow for customization of its settings. It operates based on the evaluation phase findings and limits access to apps deemed untrustworthy without offering an option to unblock them.
