How to Enable or Disable Notifications from Windows Defender Security Center in Windows 10


In Windows 10 version 1703, Microsoft introduced the Windows Defender Security Center app, which brings together common Windows security features into one app.

Windows Defender Security Center will send notifications with critical information about the health and security of your device. You can specify which informational notifications you want.

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

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

Hide all notifications - If enabled, local users will not see any notifications from the Windows Defender Security Center. This will override the Hide non-critical notification policy.

This tutorial will show you how to enable or disable notifications from the Windows Defender Security Center for all users in Windows 10.

You must be signed in as an administrator to enable or disable notifications from the Windows Defender Security Center.
