How do I stop annoying notifications and sound alerts on my screen?

You'll be able to: Turn off distracting popup banners, website notifications, and chime alerts in Windows

The steps

1
Open Windows Settings by pressing WinI. The Settings window appears on your screen.
2
Click System in the left menu, then click Notifications. The Notifications control panel opens with toggle options and a list of installed apps.

What causes most popup alerts on Windows?
Many notifications come from web browsers (like Chrome or Edge) because websites ask for permission to send updates, or from background apps you rarely use.
3
Turn the main toggle for Notifications to Off to silence all apps, or scroll down and switch off only the specific noisy apps. The selected app toggles turn gray and will no longer show banners or play sounds.
4
To temporarily block interruptions while working or watching videos, turn on Do not disturb at the top. A small bell icon with a slash appears next to your clock in the taskbar indicating quiet mode.

Tip
If popups are coming from websites inside your browser, click the lock or settings icon next to the website address in Chrome or Edge and set Notifications to Block. You can also Stop Startup Apps from opening automatically.

It looks different on my screen

On Windows 10, this feature is named Focus Assist instead of Do Not Disturb, and can be adjusted directly by opening Quick Actions (WinA).
