Windows 11 Update Disables Smart App Control: Fix Available

Microsoft's recent Windows 11 update, released on October 13, 2023, has caused some unexpected challenges for users. Following this month's Patch Tuesday, many found that the crucial Smart App Control feature had been automatically disabled.

Understanding Smart App Control

First introduced in 2022, Smart App Control aims to shield users from potentially harmful applications and files. It operates as a robust security layer, blocking any suspicious software that could compromise system integrity. However, the latest update has rendered the option to enable this feature inactive for some users.

Recognizing the Issue

In light of this situation, Microsoft has acknowledged the glitch and is currently working on a formal fix to be included in a future update. To determine if you are affected by this issue, follow these steps:

1. Open the Settings menu on your device.
2. Select Privacy & security, then navigate to Windows Security.
3. Under the Protection areas section, find App & browser control.
4. Click on Smart App Control settings to check if the option to enable it is grayed out.

If you find that the feature is indeed turned off with no option to turn it back on, you have encountered this bug.

Applying the Workaround

While waiting for an official solution, there is a temporary workaround to reactivate Smart App Control by modifying the Windows Registry. Here’s how to do it:

1. Type cmd in the search box to find the Command Prompt.
2. Right-click and select Run as administrator to ensure you have the necessary permissions.
3. In the Command Prompt window, enter the following commands:

reg add “HKLM\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides” /v 2883193997 /t REG_DWORD /d 1 /f reg add “HKLM\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides” /v 2850574478 /t REG_DWORD /d 1 /f

After you input each command, you should see a message confirming the operations were successful. Once done, close the Command Prompt and restart your computer.

Re-enabling Smart App Control

Upon rebooting, revisit the Smart App Control settings in Windows Security. You should now find that the option to enable the feature is no longer grayed out. It is advisable to keep Smart App Control active, as it significantly aids in guarding against malware and other malicious threats.

That said, if you often download files from unfamiliar sources, you might experience some inconvenience with this feature enabled. In such cases, consider turning it off temporarily—but strive to keep it activated for optimal system protection.

Final Thoughts

This incident serves as a reminder that even updates aimed at enhancing security can sometimes introduce new obstacles. Fortunately, with this workaround, Windows 11 users can regain functionality until Microsoft provides an official resolution.
