Windows 10: Windows Security Center Service and Defender not getting started in Windows 11 desktop

I am not able to start the Security Center Service and Windows Defender. I have Windows 11 installed on my desktop. I tried some solutions from the Internet but nothing worked for me. Please help me out.

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.

Windows defender security center problem

When I try to start the windows defender security center the antimalware service executable starts up and uses up to 98% CPU. I have tried to change proxy restart defender and many suggested steps and also went to windows deffender online to do a scan
that way but no malware came up. The problem still persists. Does anyone know what to do in this situation? I just want my security to run properly but I cant even get to the menus.

 

Disable Action Center in Windows 7?

Unfortunately that doesn't disable Action Center, all it does it cause Acution Center to bitch about the Security Center service not running.

Action Center seems to be a different beast from Security Center...

And telling it to not display any messages gets it out of the way, the same way disabling the icon in the suggestions above does, but Action Center is still enabled and running.
