Windows 8.1 introduced a new feature called Quiet Hours, which is also included in Windows 10. This feature allows users to delete notifications during this period. The idea behind introducing this feature is that there may be times when you don’t want to be bothered or interrupted by notifications.
Quiet hours on Windows
When you set quiet time on your Windows device, you can’t receive notifications of applications or calendar events, messages and email notifications and even take calls via Skype when the device is idle. In such situations, you will not hear any noise and the screen will not turn on due to a notification.
