We’ve had W10 machines in our enviorment for years now and had a group policy in place to disable windows defender since we have a 3rd party app doing this for us. An update in 2-2022 to Windows Defender now ignores the group policy and keeps it on. Its annoying because now we get tamper alerts from our 3rd party product. I know the quickest fix would be to put an exception for Defender but I dont want to systems in the background doing the same job taking up resources.

Link that talks about this

They also suggested reg key for passive mode but not recognized on W10 machines. Any one else experiencing the same?

Have you imported the ADMX files for your specific build of Windows 10?

Your link didn’t post, if your using Edge, CTRL+V only pastes the name, if you want to paste the link, use CTRL+ALT+V

Updated original post with link. I could be wrong but Microsoft is saying is to doesn’t matter what ADMX files you have, the default option inside of group policy to turn on defender will not work anymore, they talk about opening local group policy in the link. I could have read it wrong…

I gave up worrying about Windows Defender (I think I gave up before it was called Defender) being on at the same time as our 3rd party anti-malware software. On up-to-date, decent performing hardware, is there any user noticeable performance issue?

I realize both being active may not be optimal, but the performance to be gained vs. the effort required might be worth considering.

Since there is a service for Defender, maybe you could create a GPO to disable that service?

Defender is always on, its too deeply backed into the OS. But it goes into passive (monitoring only mode) when 3rd party AV is installed.

What is your 3rd party solution and what are the alerts you are getting?
