Add or Remove Allowed Apps for Controlled Folder Access in Windows 11

Microsoft Defender Antivirus is an antivirus software that is included in Windows 11 and can help protect your device from viruses, malware, and other threats.

Controlled folder access helps protect your valuable data from malicious apps and threats, such as ransomware. In a ransomware attack, your files can get encrypted and held hostage.

Controlled folder access protects your data by checking apps against a list of known, trusted apps. With controlled folder access in place, a notification appears on the computer where an app attempted to make changes to a file in a protected folder.

Controlled folder access works by only allowing trusted apps to access protected folders. Protected folders are specified when controlled folder access is configured. Typically, commonly used folders, such as those used for documents, pictures, downloads, and so on, are included in the list of controlled folders.

Controlled folder access works with a list of trusted apps. Apps that are included in the list of trusted software work as expected. Apps that are not included in the list are prevented from making any changes to files inside protected folders.

By default, Windows adds apps that are considered friendly to the allowed list. Such apps that are added automatically are not recorded in the list shown in the Windows Security app or by using the associated PowerShell cmdlets. You shouldn’t need to add most apps. Only add apps if they are being blocked and you can verify their trustworthiness.

Occasionally, an app that is safe to use will be identified as harmful. This happens because Microsoft wants to keep you safe and will sometimes err on the side of caution; however, this might interfere with how you normally use your PC. You can add an app to the list of safe or allowed apps to prevent them from being blocked.

You can specify if certain apps are always considered safe and give write access to files in protected folders. Allowing apps can be useful if a particular app you know and trust is being blocked by the controlled folder access feature.

When you add an app, you have to specify the app’s full path location. Only the app in that location will be permitted access to the protected folders. If the app (with the same name) is in a different location, it will not be added to the allow list and may be blocked by controlled folder access.

An allowed application only has write access to a controlled folder after it starts. For example, an app will continue to trigger events after it’s allowed until it is stopped and restarted.
