TL;DR

/Z

Does not restart the computer after the installation is completed.

/U

Uses unattended Setup mode. Requires no user interaction and shows only critical errors.

/L

Lists installed updates.

1. Add prefix numbered list to the chart

2. Mention somewhere the exact total count of updates (260…+)

3. Add a color code or icon distinction or a list sort feature to separate vulnerabilities/criticals/security from “software” updates.

4. Consider linking the direct/hotlink URL to the download if not disagreed by MS. This saves time and streamlines the download process.

5. Annex a quick note of how to use commands line available for those wanting to batch the updates manually.
