Using ConfigureDefender is simpler and safer than using a toaster.Someone made the exaggerated claim that Windows Defender at default settings has only definition checking . This is a mistake. At default settings it has behavior monitoring and script scanning and more. These functions may not be as robust as in certain other AVs, but they do exist. Those who want more aggressive protection from Windows Defender can use ConfigureDefender to enable additional mitigations and higher levels of protection. While ConfigureDefender may not be appropriate for those who think that their computer is a toaster, it is quite appropriate for anyone participating in this discussion.
