Windows 10: Windows Security Center Service has been deleted

So, I noticed that my Windows Defender wasn't functioning. It shows a black screen when I run the app.I tried powershell codes, I tried repair and reinstall. It doesn't work. I was looking for 'Windows Security Centre' in service.msc but it's not there. I think it's deleted from the Registry. Anyone please help. I have Windows 11 operating system.

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.

Hi Maninder,

I suggest you to follow the steps below and check if it helps.

• Press Windows key + R and type Services.msc then hit enter.
• Services Console will appear.
• Find Security Center Service on the right details pane > right click it choose properties >
• Security Center Properties should appear > on the General Tab

set start-up type to automatic (Delayed start)

• On service Status Stop and then Start.

If this does not works & error still continues then there are more chances that your system is infected
