tl;dr I would like Windows Update to automatically download and install only the updates "Security Intelligence Update for Microsoft Defender Antivirus".
Currently, Windows Update policy is Download the updates automatically an notify me when they are ready to be installed. However, I'd like an exception for the Microsoft Defender Antivirus. The Virus Definition updates are near-daily. I don't want to be bothered with several clicks to install them, and there is no reason to delay this install.
How can I set Windows Update to automatically install the updated virus definitions, "Security Intelligence Update for Microsoft Defender Antivirus", but not automatically install other updates?
