Permanently Turn Off Notifications in Windows 8

We already showed how you can turn off notifications in Windows 8 for a while. Maybe, you want these notifications off while you are presenting your PowerPoint slides. Although these notifications can be useful, some of them can be very irritating and even embarrassing when you show slides to an audience. Some people hate them so much that they want them barred even when they are not presenting. If your thought processes work the same way, you can turn these notifications off permanently.

Follow these steps to permanently turn off all notifications in Windows 8:

1. Access the Charms bar by pressing Windows + C, or moving your mouse cursor to the bottom right of the screen and slowly moving it up. When the Charms bar appears, click the Settings option (highlighted in red within Figure 1).
2.

3. Play notifications sounds: Turn off notification sounds.
