Windows 10 Creators Update version 1703 brought yet another change to Windows 10's UI. There is a new app called Windows Defender Security Center. The application, formerly known as "Windows Defender Dashboard", has been created to help the user control his security and privacy settings in a clear and useful way. Windows Defender Security Center got a tray icon, which is visible out of the box. If you are not happy to see it, here is a way to get rid of it.
You can launch Windows Defender Security Center from the Start menu or with a special shortcut. Alternatively, you can access it using its tray icon. As of this writing, it looks as follows:
There is a helper tool which draws the icon. It is located here:
