This tutorial will show you how to manually turn on or off Smart App Control in Windows 11.
Smart App Control (SAC) is a new security feature starting with Windows 11 build 22567. Smart App Control can work alongside your other security software, such as Microsoft Defender, for added protection.
Smart App Control adds significant protection from malware, including new and emerging threats, by blocking apps that are malicious or untrusted. Smart App Control also helps to block potentially unwanted apps, which are apps that may cause your device to run slowly, display unexpected ads, offer extra software you didn't want, or do other things you don't expect.
Smart App Control starts in evaluation mode. This is a period during which Windows tries to determine if you're a good candidate for Smart App Control. If you are a good candidate for Smart App Control, then it will automatically be turned on. If not, it'll be turned off.
Smart App Control won't block anything while it's in evaluation mode.
Once the evaluation is complete, or if you manually switch Smart App Control on or off, you won't be able to return to evaluation mode unless you reset or reinstall Windows.
In order to ensure a more secure experience Microsoft only enables Smart App Control on a clean install of Microsoft Windows 11. Microsoft wants to be sure that there aren't already untrusted apps running on the device when they turn Smart App Control on. That's why in order to turn Smart App Control back on after it's been turned off, you'll need to reset or reinstall Windows.
There is currently no way to bypass Smart App Control protection for individual apps. You can turn Smart App Control off, or (better yet), contact the developer of the app and encourage them to sign their app with a valid signature.
Smart App Control is only available on clean installs of Windows 11. Also, there are other reasons why Smart App Control could be turned off.
- During evaluation mode Microsoft determined that you weren't a good candidate for Smart App Control.
- It was turned off manually by you or another user signed into your machine.
- Your device is running Windows in S mode. You'll need to turn S mode off, then reset your PC, to enter evaluation mode.
- You have optional diagnostic data in Windows turned off. If you want to turn Smart App Control on, you'll need to reset this PC, or reinstall Windows, and select Send optional diagnostic data during the setup process.
