删除 Windows Defender 图标

早些时候，在Window 10中，Windows Defender在后台静默运行，不显示系统托盘图标，只有当有需要注意的事情时，您才会看到该图标并收到通知。但现在它一直显示。

如果您打开任务栏^(Taskbar)，在进程^(Process)选项卡下，您将看到一个Windows Defender通知图标进程– MSASCuiL.exe。您可以右键单击它以结束该过程，但是当您重新启动计算机时，它可能会再次出现。

您需要做的是，打开“启动^(Startup)”选项卡并禁用Windows Defender通知图标条目。为此，请选择条目并按禁用按钮。

Windows Defender图标将被删除。

阅读^(Read)：即使安装了第 3 方防病毒软件，Windows Defender 也不会关闭^{(Windows Defender will not turn off even when 3rd party AntiVirus is installed)}。

即使安装了第 3 方防病毒软件^(Antivirus)，也会显示Windows Defender通知图标

现在这是发生在我身上的情况。我安装了第 3 方安全套件，但Windows Defender图标过去总是显示在Notification Area中。

Windows Defender已关闭，定期扫描^{(Periodic Scanning)}功能也已关闭 - 但图标不会消失。

我可以在任务管理器中看到^{(Task Manager)}Windows Defender通知图标进程作为正在运行的进程，但它没有显示在任务管理器的启动^(Startup)选项卡下。

那么我怎么能禁用这个图标呢？我能做什么？

好吧，如果您遇到此问题，请从WinX 菜单^{(WinX Menu)}中打开设置^(Settings)>个性化，然后在左侧窗格中选择任务栏。^(Taskbar)向下滚动^(Scroll)并单击选择哪些图标出现在任务栏^{(Select which icons appear on the taskbar)}链接上，以打开以下窗口。

在这里您将看到Windows Defender 通知图标^{(Windows Defender notification icon)}。将开关切换到关闭^(Off)位置，您将看到Windows Defender图标从系统托盘^{(System Tray)}中消失。

这对我有帮助，希望对你也有帮助。^{(This is what helped me, and hope it helps you too.)}

如果这对您没有帮助，请打开注册表编辑器^{(Registry Editor)}并导航到以下键：

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

创建一个新的字符串值，将其命名为Windows Defender并将其值设置如下：

"%ProgramFiles%\Windows Defender\MSASCuiL.exe"-runkey

重启你的电脑。

该图标应该已被禁用。

Remove Windows Defender Notification Icon in Windows 10

Windows 10 Anniνersarу Update v1607 and later will now display the Windows Defender icon in the Notification Area of yоur taskbar. In thіs poѕt, we will see how to hidе, disable or remove the Windows Defender icon from the System Tray when you have enabled Windows Defender – as well in a situation, where the Windows Defender Notification Icon still shows, even when you have a 3rd-party antivirus software installed.

Remove Windows Defender Icon

Earlier, in Window 10, Windows Defender ran silently in the background, without displaying the system tray icon, and you would see the icon and be informed only if there was something which needed your attention. But now it displays all the time.

If you open the Taskbar, under the Process tab, you will see a Windows Defender notification icon process – MSASCuiL.exe. You can right-click on it to end the process, but when you restart your computer, it may appear back.

What you need to do is, open the Startup tab and disable the Windows Defender notification icon entry. To do this, select the entry and press the Disable button.

The Windows Defender icon will be removed.

Windows Defender notification icon displays even with 3rd party Antivirus installed

Now here is the case which happened to me. I have a 3rd-party security suite installed, and yet the Windows Defender icon used to be always displayed in the Notification Area.

Windows Defender was turned off and so was the Periodic Scanning feature – yet the icon would not go away.

I could see the Windows Defender notification icon process in the Task Manager as a running process, but it was not being displayed under Startup tab of the Task Manager.

So how could I disable the icon? What could I do?

Well if you face this issue, from the WinX Menu, open Settings > Personalization and select Taskbar in the left pane. Scroll down and click on Select which icons appear on the taskbar link, to open the following window.

Here you will see Windows Defender notification icon. Toggle the switch to the Off position and you will see the Windows Defender icon disappear from the System Tray.

This is what helped me, and hope it helps you too.

If this does not help you, open Registry Editor and navigate to the following key:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Create a new string value, name it Windows Defender and set its value as follows:

"%ProgramFiles%\Windows Defender\MSASCuiL.exe"-runkey

Restart your computer.

The icon should have been disabled.
