Windows Defender Security Center is not to be confused with Windows Defender which automatically disabled itself when you install any supported antivirus software. When hovering the mouse over the icon, most of the time the tooltip will pop up stating no actions needed, as your own comprehensive security software takes care of most protection needs. In Windows 10 Creators Update v.1703 (Build 15063) or later, a Windows Defender Security Center icon always appear in the notification area of Taskbar (system tray), even though you are relying on third party antivirus solution to protect against virus and threats, and have not been using Windows Defender.
