How to enable / disable notifications from Windows Security Center in Windows 10

In this article, TipsMake will guide you on how to enable or disable notifications from Windows Security Center in Windows 10.

You can hide notifications since Windows 10 version 1709

Starting with Windows 10 version 1709, you can enable the Hide non-critical notification policy or Hide all notifications.

Hide non-critical notification - If enabled, only important notifications will show up from Windows Security. Local users will only see important notifications from Windows Defender Security Center. They won't see other types of notifications, such as regular PC or device health information.

Hide all notifications - If enabled, local users won't see any notifications from Windows Security. This will override the Hide non-critical notification policy.
