I ran Microsoft Baseline Security Analyzer because I'm getting error 80072EFD while trying to run Windows Update, and the troubleshooter can't fix it as of Oct 2019. So, there are some updates that haven't downloaded and thus haven't been installed, when I ran wsusoffline1181 on WIndows 7 ultimate.
Microsoft Baseline Security Analyzer wanted KB4507004, KB4507411, and KB4514602, amongst others, and when I ran wsusoffline1181, it installed the other updates but didn't install these ones because it didn't download them:
