How to Completely Disable ‘Focus Assist’ (Do Not Disturb) Automatic Rules in Windows 11

Windows 11 includes a feature called “Focus Assist” (recently rebranded simply as “Do Not Disturb” in newer updates), which is designed to suppress notifications and banners so you can concentrate on your work. To be “helpful,” Microsoft enabled several automatic rules by default. For example, the moment you duplicate your display to a projector, or launch a video game in full-screen mode, Windows will automatically turn on Do Not Disturb without asking you.

While this sounds great in theory, it can be disastrous if you rely on critical Slack messages or email alerts while presenting a slide deck on a secondary monitor, or if you are playing a windowed-borderless game and miss an urgent calendar reminder. If you want absolute, manual control over when your notifications are muted, you must completely disable these automatic triggers.

Disabling the Automatic Do Not Disturb Rules

You can turn off these hidden triggers directly from the main Windows 11 System Settings, ensuring that notifications always pass through unless you explicitly click the mute button yourself.

1. Click the Start button and select the Settings gear icon (or press Windows Key + i).
2. In the left-hand sidebar of the Settings app, ensure you are on the System tab.
3. In the main panel, click on Notifications.
4. Scroll down to the section labelled Do not disturb (if it is collapsed, click the arrow to expand it).
5. Look for the sub-section labelled Turn on do not disturb automatically.
6. You will see several checkboxes outlining specific scenarios. To completely stop the operating system from making decisions for you, uncheck every single box in this list, including:
   • During these times (scheduled hours)
   • When duplicating my display (presenting)
   • When playing a game
   • When using an app in full screen mode

The changes take effect immediately. From now on, whether you are presenting to a boardroom or launching a full-screen application, your critical notifications will always break through. The only way Do Not Disturb will ever activate is if you manually click the crescent moon icon in your system tray.
