@Corrine, I didn't consider this, and yes it does download it and get it ready to install, but it sets the restart out of the Active Hours (though it still gives you the option to restart right now, or to schedule it for this time to be different than Active Hours).
@Dr M, Wait for tomorrow, and let Windows find the updates. You can open Settings and go to Windows Update, but don't click Check for Updates. Because these updates are security updates, don't use Internet Explorer or Edge, and I don't want to delay this too much either, so if it doesn't check the updates by tomorrow, then do a check and install it on Thursday
