Windows 11 S mode av updates
Father has Windows 11 in S mode. When installing Security Intelligence update for Microsoft Defender gets "error encountered", which then changes to "completed". Update history states "successfully installed" on related entry. How can something be successfully installed if an error occurred during the install - that does not make sense. Am obviously nervous now that the av is not being updated properly. Any suggestions?

Think of the Security Intelligence Update (KB2267602) as a rapid-fire definition update—Microsoft releases these multiple times per day to keep your antivirus current. The update process involves several internal checks before the installation finalizes. Windows Update may flash the "error encountered" message if any single step (a network delay, a service handshake, or the scanning engine swapping) takes a little longer than expected. This message is generally a red herring—the update engine recovers instantly and completes the installation.
