    Hi @Glenn Maxwell

    It's not always as easy as running the command, but that would remove Windows Defender from the server. There are times (as seen in https://social.technet.microsoft.com/Forums/office/en-US/00b84b96-967b-4920-98b0-2c5cd90debb5/problems-uninstalling-windows-defender-feature-from-server-2016?forum=ws2016) where you also need to remove certain KBs to remove Defender.

    I don't see the harm of removing defender, but you should be aware of which patches you're installing in the future as some of them might re-enable Defender.

    I do not use Defender on my servers and use a third-party antivirus (endpoint protection).

    Hello there,

    You do not need to uninstall the defender.
    If you have another antivirus app installed and turned on, Microsoft Defender Antivirus will turn off automatically. If you uninstall the other app, Microsoft Defender Antivirus will turn back on automatically.
