Setting Up Smart App Control for Enhanced Windows 11 PC Security

Activating Smart App Control in Windows 11: Your Step-by-Step Guide

Smart App Control is a pivotal built-in security feature designed for Windows 11 that helps safeguard your computer by automatically blocking applications that are potentially harmful or untrustworthy. This feature utilizes advanced machine learning and extensive security intelligence from Microsoft to determine an app’s safety, significantly reducing the risk of malware infections and unwanted software installations. By activating Smart App Control, you are taking a vital step towards fortifying your system against various security threats.

1. Check Your System Compatibility and Status

Before activating Smart App Control, it’s essential to ensure that your system meets the required specifications. The feature is only available on Windows 11 versions 22H2, 23H2, 24H2, and newer versions. It’s crucial to note that Smart App Control is designed for clean installations; it does not function on systems upgraded from Windows 10. Furthermore, your device must have Secure Boot and TPM 2.0 support.

To check your current status for Smart App Control, follow these simple steps:

Press the Windows key, type Windows Security, and hit Enter to open the Windows Security app.
Navigate to App & browser control and select Smart App Control settings to see if the feature is active, in evaluation mode, or disabled.

2. Method 1: Activate Smart App Control via Windows Security

The most straightforward method to activate Smart App Control is through the Windows Security application.

Follow these steps:

Step 1: Open the Start menu, type Windows Security, and select the app.
Step 2: Click on App & browser control from the left-hand menu.
Step 3: Under the Smart App Control section, access the Smart App Control settings.
Step 4: Choose Evaluation mode. This will allow Smart App Control to monitor your applications without immediate blocks and adjust itself based on the evaluation period findings.
Step 5: If no issues arise during the evaluation, Smart App Control will enable automatically.

3. Method 2: Enable Smart App Control Using the Registry Editor

If accessing Windows Security is not feasible, you can manually enable Smart App Control through the Registry Editor. It’s crucial to back up your registry settings before you proceed to avoid potential complications.

Here’s how to do it:

Step 1: Open the Run dialog by pressing Windows + R, type regedit, and hit Enter.
Step 2: Navigate to this path in the Registry Editor: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CI\Policy.
Step 3: Double-click on the key named VerifiedAndReputablePolicyState; if it doesn’t exist, create it by right-clicking in the right pane and selecting New > DWORD (32-bit) Value, then entering the name.
Step 4: Modify the value data to 1 to enable Smart App Control or 2 to activate Evaluation mode. Click OK and restart your computer to apply the changes.

4. How Smart App Control Works

Once activated, Smart App Control meticulously evaluates each application that tries to run on your device. Utilizing Microsoft’s cloud-based intelligence, it assesses the safety of apps based on digital signatures, publisher reputation, and observed behavior. If an application is deemed potentially dangerous, Smart App Control intervenes and blocks it while notifying you of the action taken.

Note that Smart App Control lacks an unblocking option for individual apps. Therefore, if a legitimate application is erroneously blocked, disabling the feature may be necessary, which requires either resetting or reinstalling Windows 11 while giving the option to keep your files.

5. Disabling Smart App Control

If Smart App Control becomes too restrictive and prevents the execution of trusted applications, it can be disabled. However, keep in mind that once deactivated, reactivation requires a clean installation or system reset of Windows 11.

To disable Smart App Control:

Navigate to the Windows Security > App & browser control > Smart App Control settings.
Select the option Off and confirm when prompted.

Beware that disabling this security feature increases the risk of malware infections and other security threats, so proceed with caution.

6. Best Practices for Using Smart App Control

To enhance the efficacy of Smart App Control, follow these best practices:

Regularly update your Windows 11 system to acquire the latest security patches and definitions.
Download and install applications exclusively from trusted sources, such as the Microsoft Store or recognized software publishers.
Keep Smart App Control activated whenever feasible, especially after installing new software or when navigating unfamiliar websites.
Use Smart App Control in conjunction with additional security measures, like reputable antivirus solutions and robust firewall settings, for comprehensive protection.

By activating Smart App Control, you are strategically protecting your Windows 11 PC from malicious applications and potential security threats. This simple yet powerful adjustment is crucial for sustaining a secure computing environment.
