How to Allow Apps in Windows 11 Controlled Folder Access

This guide explains how to let specific apps use your protected folders using Microsoft Defender Antivirus in Windows 11.

Controlled folder access is a security feature that stops harmful programs and threats like ransomware from changing your personal files.

Why do this?

Sometimes, Windows 11 blocks a safe app because it thinks the app is a threat. By adding that app to your “allowed” list, you tell Windows that the program is safe to use. This keeps your files protected while letting your trusted apps work normally.

What happens when done?

Once you add an app to the list, it can read and write to your protected folders without being blocked. Ransomware will still be blocked by default, keeping your data safe from being locked by hackers.

Allowing apps through Controlled folder access

You can add apps that are being blocked by following these steps:

1. Click the search box on your taskbar, type Windows Security, and click Windows Security.

2. Click Virus & threat protection.

3. Look for Ransomware protection and click Manage ransomware protection.

4. Make sure Controlled folder access is turned On.

5. Click the link that says Allow an app through Controlled folder access.

6. Click Add an allowed app. Find the program you want to allow on your computer and click Open.

Managing access with Group Policy (Advanced)

Note: This section requires admin privileges.

You can also control these settings using the Group Policy Editor.

1. Open the Start menu, search for Local Group Policy Editor, and select Edit group policy.

2. In the menu on the left, go to: Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus > Microsoft Defender Exploit Guard > Controlled folder access.

3. Double-click Configure allowed applications on the right side.

4. Select Enabled and click Show to list the specific programs you want to allow.

When you are finished, click OK and close the window.

Summary

Controlled folder access is a great way to protect your documents from ransomware. If a safe app gets blocked, simply add it to your allowed list using the Windows Security settings. This keeps your computer secure while making sure your favorite apps run without any errors.
