Disable Windows Lock Screen Camera Using Registry

This article explains how to control and disable the lock screen camera feature in Windows using the Registry Editor (Regedit). By navigating to the designated system policy key and creating or modifying a specific DWORD value, administrators and users can prevent the camera from being accessed while the device is locked, improving device security and privacy.

The Registry Path and Value

The behavior of the Windows lock screen camera is controlled through the following registry location:

• Registry Path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization
• Value Name: NoLockScreenCamera
• Value Type: REG_DWORD (32-bit Value)
• Value Data:
  • 1 = Disables the camera on the lock screen.
  • 0 = Enables the camera on the lock screen (default behavior).

Step-by-Step Instructions

1. Press Windows Key + R to open the Run dialog box.

2. Type regedit and press Enter (select Yes if prompted by User Account Control).

3. In the Registry Editor address bar, navigate to:

   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows

4. Check if the Personalization key exists under Windows. If it does not exist:

   • Right-click the Windows folder.
   • Select New > Key.
   • Name the new key Personalization.

5. Select the Personalization key.

6. In the right pane, right-click an empty space and select New > DWORD (32-bit) Value.

7. Name the new value NoLockScreenCamera.

8. Double-click NoLockScreenCamera, set the Value data to 1 to disable the lock screen camera, and click OK.

9. Restart your computer or lock Windows (Windows Key + L) for the changes to take effect.

Quick Method via Command Prompt

To apply this registry change quickly without opening the Registry Editor interface, run Command Prompt as an Administrator and execute the following command:

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization" /v NoLockScreenCamera /t REG_DWORD /d 1 /f

To revert the change and re-enable the camera, run:

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization" /v NoLockScreenCamera /t REG_DWORD /d 0 /f
