Disable Windows Defender Security Center Tray Icon

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:

"C:\Program Files\Windows Defender\MSASCuiL.exe"

This file runs at startup when you sign in to your Windows 10 account and so the icon appears in the tray. To get rid of the icon, you can remove MSASCuiL.exe from startup. This operation has no side effect and will disable the tray icon completely.

To disable Windows Defender Security Center tray icon, do the following.

To remove MSASCuiL.exe from startup, we will use the methods described in the article How to add or remove startup apps in Windows 10.

    Is it possible at all to disable Windows Defender Security Center through the registry or group policy since the ability to turn off the service is grayed out?

    This icon should be manageable from Settings pane to enable or disable system notification area icons, as WDSC is for many things that the classic Security and Maintenance (formerly Action Center) Control Panel applet. Even when in Windows 10 they call Action Center to notification and quick action repository, former Action Center (w7-8.1) had a notification area icon that was turnable on or off by this setting.
