Windows Security Center service stops

Hi Jalil,

1. Are you getting any error message?
2. Have you made any recent changes to the computer?

Method 1:

I would suggest you to make the “Windows defender Service” startup type to “Automatic”.

Follow these steps:

a. Press “Windows key + R” from keyboard.

b. Type “services.msc” without quotes in the “Run” Window and hit enter.

c. Search for “Windows Defender Service”.

d. Make “Startup Type” to “Automatic”.

e. Restart the computer and then check how it works.

Method 2:

Perform System File Check (SFC), and then check if this fixes the issue.

Follow the steps:

a. Press “Windows Key + Q” to open Charms Bar.

b. Type “cmd” without quotes in the search box.

c. On the left pane, right click on the “cmd” option and select “Run as Administrator”.

d. Type ‘sfc /scannow’ without quotes and hit enter.

Note: It may ask for windows installation DVD to fix and to enable SFC to make more than minor repairs. Some files saved on your computer might get deleted when fixing corrupted files.

You can refer to the article mentioned below if the issue persists.

Please reply with the results. I would be glad to assist you further.

I've tried your methods, I've noticed that my windows defender service is running okay at the time when the error appears in my action center. My firewall is also enabled and working fine, but the error says "Windows security center service stopped".
