How to Enable Controlled Folder Access in Windows 10 & 11

Reading Time: 5 minutes

Keep your files safe with Controlled Folder Access for Windows.

Controlled folder access is a feature of the Windows Security antivirus app on Microsoft desktop platforms. That feature forestalls ransomware by preventing modifications to files in protected folders. Enabling controlled folder access prevents untrusted apps, malware or otherwise, from changing files within protected directories.

Controlled folder access is an extra security feature in Windows 10 and 11 that some users appreciate. Ransomware isn’t something to be taken lightly, and enabling that feature will keep system and user files extra safe. These are four ways you can enable controlled folder access in Windows.

How to Turn On Controlled Folder Access in Windows Security

The Controlled folder access setting is buried within ransomware protection in the Windows Security app. However, it’s easy to find and turn that option on/off when you know where it is. This is how to turn on the Windows Security’s app Controlled folder access option.

1. To view the Windows Security app, double-click its shield system tray icon.
2. Select Windows Security’s Virus & threat protection tab.
3. Click Manage ransomware protection to reach the Controlled folder access setting.
4. Now turn on the Controlled folder access option to enable that feature.

Controlled folder access protects your Documents, Videos, Pictures, and Music user folders when enabled. To view the list of protected user directories, click Protected folder. You can add more to the list by clicking the Add protected folder button, choosing a directory, and clicking Select Folder.

How to Turn on Controlled Folder Access With PowerShell

Windows PowerShell gives you an alternative method to enable and disable controlled folder access by executing commands. You can turn on controlled folder access with PowerShell as follows:

1. To activate a file search tool, press Win + S.
2. Input PowerShell within the activated search utility.
3. Open PowerShell in an elevated mode by selecting Run as administrator.
4. To enable controlled folder access, input this command text and hit Enter:

    Set-MpPreference -EnableControlledFolderAccess Enabled 

5. You can disable controlled folder access by executing this command:

    Set-MpPreference -EnableControlledFolderAccess Disabled 

How to Enable Controlled Folder Access With Group Policy Editor

If you have Windows 11 Pro or Enterprise edition, you can enable controlled folder access with Group Policy Editor. Group Policy Editor also includes some extra configuration settings for controlled folder access, which is a bonus. This is how to turn on controlled folder access via GPE.

1. Bring up the search tool in Windows and enter gpedit.msc there.
2. Select gpedit.msc to bring up the Group Policy Editor.
3. Click Computer Configuration > Administrative Templates inside Group Policy Editor’s left pane.
4. Double-click Windows Components to expand it.

7. Then double-click Configure Controlled folder access to view that setting’s window.
8. Select the Configure Controlled folder access window’s Enabled radio button.
9. Click Block on the drop-down menu to select the strictest CFA mode. However, you can also select alternative Audit Mode, Block disk notification only, and Audit disk notification only options for enabling controlled folder access.
10. Select Apply in the Configure Controlled folder access window.
11. Click the Configure Controlled folder access window’s OK button.

How to Turn on Controlled Folder Access From the Windows Context Menu

Alternatively, you can create a context menu shortcut for enabling/disabling controlled folder access. Then you’ll be able to access a Turn on Control folder access setting directly from the desktop area of Windows. You can add such a CFA option to the right-click menu by setting up and running a registry script like this:

1. Open Notepad.
2. Then select this script text, and press the Ctrl + C key combination:

    Windows Registry Editor Version 5.00

    [HKEY_CLASSES_ROOT\DesktopBackground\Shell\ControlledFolderAccess]
   
    'HasLUAShield'=''
   
    'Icon'='%ProgramFiles%\\Windows Defender\\EppManifest.dll,-101'
   
    'MUIVerb'='Turn On or Off Control folder access'
   
    'Position'='Bottom'
   
    'SubCommands'=''
   
    
   
    
   
    [HKEY_CLASSES_ROOT\DesktopBackground\Shell\ControlledFolderAccess\shell\001flyout]
   
    'MUIVerb'='Turn on Control folder access'
   
    'HasLUAShield'=''
   
    'Icon'='%ProgramFiles%\\Windows Defender\\EppManifest.dll,-101'
   
    
   
    [HKEY_CLASSES_ROOT\DesktopBackground\Shell\ControlledFolderAccess\shell\001flyout\command]
   
    @='PowerShell -windowstyle hidden -Command \'Start-Process cmd -ArgumentList '/s,/c,start PowerShell.exe Set-MpPreference -EnableControlledFolderAccess Enabled' -Verb RunAs\''
   
    
   
    
   
    [HKEY_CLASSES_ROOT\DesktopBackground\Shell\ControlledFolderAccess\shell\002flyout]
   
    'MUIVerb'='Turn off Control folder access'
   
    'HasLUAShield'=''
   
    'Icon'='%ProgramFiles%\\Windows Defender\\EppManifest.dll,-101'
   
    
   
    [HKEY_CLASSES_ROOT\DesktopBackground\Shell\ControlledFolderAccess\shell\002flyout\command]
   
    @='PowerShell -windowstyle hidden -Command \'Start-Process cmd -ArgumentList '/s,/c,start PowerShell.exe Set-MpPreference -EnableControlledFolderAccess Disabled' -Verb RunAs\'' 

3. Paste that script into Notepad by clicking in that app’s window and pressing Ctrl + V.
4. Next, press Ctrl + Shift + S to view Notepad’s ‘Save as’ window.
5. Set the Save as type option to All files.
6. Type Turn on Control folder access.reg inside the file name box.
7. Select to save the script to the desktop location.
8. Click Save to add the Turn on Control folder access registry file to the desktop.
9. Close the Notepad editor, and double-click the Turn on Control folder access.reg file on the desktop.
10. Select Yes to confirm you trust the script.

Now you can enable controlled folder access from the Windows context menu.

Right-click any clear area of the desktop and select Show more options on Windows’ context menu. Move the cursor over the Turn On or Off Control folder access submenu. Click Turn on Control folder access to enable that Windows Security feature.

If you ever want to remove the controlled folder access context menu option, you can do so by deleting the registry key for it. This is how to delete the key for the Turn On or Off Control folder access submenu:

1. Launch the Registry Editor (our guide for opening the Regedit registry app includes various methods).
2. Go to this registry key location:

    HKEY_CLASSES_ROOT\DesktopBackground\Shell\ControlledFolderAccess 

3. Right-click the Controlled Folder Access key to select Delete.
4. Click Yes to erase that key.

How to Set Controlled Folder Access Exceptions

The problem with controlled folder access is that it can stop legitimate apps from accessing required files when they need to. That can be an especially big issue for Windows gaming since untrusted games often can’t save progress with controlled folder access enabled. In-game settings can also reset when that feature is turned on.

Fortunately, controlled folder access has an exclusion (exception) list for adding trusted apps. It won’t block any trusted apps on that list from modifying files within protected folders. You can add software to the CFA exclusion list as follows:

1. Bring up the Controlled folder access setting in Windows Security as covered in steps one to three of the first method above.
2. Click the Allow an app through Controlled folder access navigation link.
3. Press the + Add an allowed app button.
4. Click Browse all apps on the menu that appears.
5. Select the EXE (application) file for a game or other software you want to exclude from controlled folder access.
6. Click Open to add the selected game or software.

Enable Controlled Folder Access for Greater Ransomware Protection

Turning on controlled folder access in Windows 10 and 11 with the above methods will give files on your PC an extra layer of protection from malware. It makes little difference how you enable that feature, but you can select more configuration options by using Group Policy Editor. Adding controlled folder access context menu settings also gives you a more direct way to toggle that feature on/off as required.
