Windows 10: Is it okay if the Windows Defender Service is not running and is set to Manual?

I'm just wondering what's wrong with Windows Defender on my computer. It works perfectly fine. Scanning is working. Like what you see in the image below, everything is GREEN.But the problem is, the Windows Defender Service. Please refer to the image below. Like what you see, the Windows Defender Firewall is running. It is working perfectly. But when you look at the item above it, the Windows Defender Advanced Threat Protection Service, it isn't running and is set to Manual.I tried everything I found on the Internet to make the service running, but none worked, including the ones I found here i

:)

 

Windows Defender isn't initializing.

Hi Abdul,

Thank you for using Windows 10.

Sorry for the delayed reply. I suggest you to Set Windows Defender to Automatic - You can set the Windows Defender service to Automatic, Disabled or Manual. Setting it to automatic might solve the problem. Follow these
steps:

• Click Start > type services in the Search box > click Services in the Programs list.
• Search for Windows defender.
• Double-click Windows Defender, and click Automatic in the start-up box > click OK.

Also, follow the below mentioned steps and check:

• Open the Task manager. Here’s a tip: Press CTRL+Shift+ESC.
• Click File > Run New Task
• Make sure you have a check mark beside “Create this task with administrative privileges”
  
• Type CMD
• Type the following 2 commands at the CMD prompt:
  
  dism /online /cleanup-image /restorehealth
  
  sfc /scannow
  
  
• Close the CMD window

Keep us posted on the status of the issue and we’ll be glad to help.

windows defender & security center services keep turning off


Are you running any other AV or did you have one running in the past? If you didn't use an uninstaller for the AV, then the remnants of it could be causing the problem. Normally any time you install an AV it disables Defender by default.

If you are getting any error codes please list those, that will be helpful in helping you.

As torre suggested, might be a good idea to do a reset or even a reinstall.
