Windows 10: Is Windows Defender Running All the time?

I've just upgraded to Win 10 and I am slowly figuring out where everything is.
I also like to set certain apps to be visible in the Tray.
Windows Defender is one of those I have set to be visible all the time.

When I restart, it's not there.

I go to Settings>Update & Security>Windows Defender . . . and scroll to the bottom and click on the "Use Windows Defender" link and it pops up and appears in the Tray. When I close the window it stays in the tray.

When I shut-down and restart, it's gone (doesn't appear in the tray on the restart).

Am I missing something?
I shouldn't have to click the "Use Windows Defender" link every time I start should I?

Thanks for the help.

:)

 

windows defender running all the time around 20%

Answer-by-number:

1. Did the computer come with Win10 preinstalled, did you do a clean install of Win10, or did you upgrade a Win7 computer or a Win8.1 computer [<=PICK ONE!] to Win10?

2. Who manufactured the computer (e.g., Dell; HP; Acer; Lenovo; ASUS)?

3. Has a Norton application or a McAfee application EVER been installed on the computer since you bought it?

4. Have you ever run the Norton Removal Tool and/or the
McAfee Consumer Products Removal Tool?

5. What Version & OS Build of Windows 10 is currently installed? See METHOD 1 on this page =>

Flag says "Sub received bad data"

Any ideas?

 

To get Defender to appear on the taskbar go to Settings>System>Notifications and actions>Select which items appear on the taskbar. turn on windows defender.

 

Yep. I did all of that. And yet when I restart, it is not there. The settings haven't changed, and the only way to get it to show again is to click the "Use Windows Defender" link again.

I don't know why it's not sticking, and why I asked the original question:
Is Windows Defender Running All the time?

(ie on startup)

This is a clean install and not an upgrade - not that that should matter - and is a brand new laptop.

Defender should be running all the time. You might want to go to the control panel(Rt click on windows logo in lower left corner),
click on review your computers status under System and Security and then click on the Security section. It will tell you about defender as well as the firewall etc.

 

Will do when I get home. Still seems Odd that if it IS running and have asked it to show the icon that it doesn't appear. Thanks for the reply and will report back.

Per chance, if you set it to show the icon on your machine and you restart does it appear or does it stay hidden until you make the selections I have mentioned above?

Thanks again for the input.

 

I just restarted my computer and sure enough the defender icon disappears too. I checked in "Select which items to appear on the taskbar" and the defender switch is turned on. I'll report it using the feedback app to MS, you might want to also.

 

Will do. Thanks for checking it. I thought maybe I was missing something. I guess as long as we can see it as one of the running processes we should be good knowing it is indeed 'on' . . . would you agree?

 

Yes, Defender does keep working even if the icon isn't showing. You can check in task manager also to see that it is running. (RT click on the windows icon and select task manager from the menu, click on the services tab and look for WinDefend).

 

Yes it does keep on running in the background.

The icon appears in the Notifications area after it has been opened but will disappear after a logoff or reboot - this is normal behaviour for Windows 10.

If you want it running all the time, then please follow these instructions: Windows Defender Notification Area Icon - Hide or Show in Windows 10 - Windows 10 Forums
