Prevent Windows 10 Professional from rebooting my computer in the middle of the night

Since upgrading to Windows 10 on all my home machines, I have found my computers restarted in the middle of night due to Microsoft's highly aggressive automatic updates. I wasn't able to find a way to do anything except manually delay a reboot. This is bad news for my servers which I do not want restarted randomly and also bad news for my desktop since I often leave work unfinished and work at random hours. I finally found a setting in the Local Group Policy Editor that appears to be what I need: "No auto-restart with logged on users for scheduled automatic updates installations"

This setting is under Computer Configuration - Administrative Templates - Windows Components - Windows Update.

(Previously, I tried changing "Configure Automatic Updates" as suggested by another website, but even with that setting changed, I found my server rebooting in the middle of the night.)
