How to Hide Lock Screen Notifications in Regedit

Managing lock screen notification privacy in Windows can be handled directly through the Windows Registry Editor. This guide details the specific registry keys and DWORD values used to hide or display toast notifications on the lock screen for the current user or across the entire system.

User-Level Registry Setting

The primary registry entry controlling whether notifications appear above the lock screen for the logged-in user is located in the CurrentVersion\Notifications\Settings path.

• Registry Path: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Notifications\Settings
• Value Name: NOC_GLOBAL_SETTING_ALLOW_TOASTS_ABOVE_LOCK
• Value Type: REG_DWORD
• Value Data:
  • 0 = Hide notifications on the lock screen
  • 1 = Show notifications on the lock screen

How to Apply the Setting:

1. Press Windows Key + R, type regedit, and press Enter.

2. Navigate to:

   HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Notifications\Settings

3. Locate the DWORD named NOC_GLOBAL_SETTING_ALLOW_TOASTS_ABOVE_LOCK. If it does not exist, right-click an empty area, select New > DWORD (32-bit) Value, and name it accordingly.

4. Double-click the value and set the Value data to 0 to hide notifications, or 1 to allow them.

5. Click OK and restart Windows Explorer or sign out for changes to take effect.

Policy-Level Registry Setting (System-Wide)

To enforce this setting across the entire machine or prevent users from changing lock screen notification preferences via the Settings app, you can use the policy-based registry key.

• Registry Path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System
• Value Name: NoToastApplicationNotificationOnLockScreen
• Value Type: REG_DWORD
• Value Data:
  • 1 = Disable and hide all toast notifications on the lock screen
  • 0 (or deleted) = Allow notifications on the lock screen

How to Apply the Policy:

1. Open the Registry Editor (regedit).

2. Navigate to:

   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System

3. Right-click the System key, choose New > DWORD (32-bit) Value, and name it NoToastApplicationNotificationOnLockScreen.

4. Double-click the newly created entry and set its value to 1.

5. Click OK and restart your computer.
