How to turn on or off Notifications for Reminders and VoIP calls on Lock Screen in Windows 11

Lock screen notifications in Windows 11 show alerts from apps like Skype or Microsoft Teams directly on your sign-in screen before you unlock your computer. Turning this feature on or off lets you control what private information appears on your display and keeps your personal data hidden when you walk away from your PC.

Manage these display preferences through the Windows 11 Settings app ⚙️ to choose which apps can show reminders and voice over IP (VoIP) calls. You can hide all alerts or pick one specific app to show details while your device stays locked.

Open the Settings app by pressing the Win plus I on your keyboard, then click on System to find your lock screen options and adjust your alerts without touching any system files.

1. Open Settings. You can do this by pressing the Win+I on your keyboard.
2. Click on System in the left-hand menu.
3. Then, click on Notifications on the right side.
4. Under the “Notifications” section, click on Notifications to expand it.

Keeping reminders and VoIP calls active ensures you never miss important updates, while hiding them gives you a cleaner and more private lock screen. You can change these settings at any time using either the Settings app or the Registry Editor depending on your preference.

Enabling lock screen notifications forces reminders and VoIP (Voice over Internet Protocol) calls to appear on the Windows 11 lock screen. Disabling the feature hides them from the lock screen, though the PC still displays the notifications after unlocking.
