So to clarify.. When new version is available simply download and run - no need to delete existing version?It doesn't update by itself. It's a portable app so nothing to install. @Andy Ful always announces the latest version and posts the download links here or you may go to GitHub - AndyFul/ConfigureDefender: Utility for configuring Windows 10 built-in Defender antivirus settings. to get the latest.
If you use CD by itself* you may want to consider his RunBySmartscreen, which is another useful tool.
*Note: ConfigureDefender is also included with Hard_Configurator Windows hardening application, which is a complete package as a separate option. His GitHub page has all of his tools.
