Thanks, Servocrow. In my case I had to stop and disable the Windows Update service, but your post put me on the right track.
My Win7 Pro x64 desktop had not been able to install updates since roughly March or April 2016. The Window update agent was running constantly, fully saturating one core of an Ivy Bridge I5 running at 4.1 GHz. So I ran the download portion of wsusoffline, then erased my C:\ drive SSD by running the clean command in DiskPart, and did a clean re-install of the OS. But when I ran the update portion of wsusoffline, it was still hung at the "listing of missing updates" stage after 21 hours. Your net stop suggestion didn't end the hang, but stopping the service, disabling the service, and restarting the computer got wsusoffline going immediately.
I ran wsusoffline a second time to make sure nothing had been skipped. Then I enabled the Windows Update service, started it, and tried a download of updates in Windows Update. Somehow, it worked perfectly and displayed about 60 updates, mostly drivers and non-security Windows updates. I've installed the drivers and security updates, but I won't install any of the roughly 40 non-security, non-critical updates without looking them up and making sure I really need them. Then I'll disable the Windows Update service again.
Many thanks to the creators of wsusoffline and the posters to this forum for getting my computer updated again. Note to the moderator: there are currently three separate threads on this same subject. This is the main thread. Maybe the other two could be wrapped in.
