Thanks! Another wrinkle.
All I have for the
entire update history in the machine is now this. When I dive into the bottom ones, it seems like the earliest the files inside them date back to is April 2016.
That ^^^^ is all there is. That can't be right.
CAN IT?????
In the process of mucking with this for days, (by following instructions) the following has been renamed so that they would be generated from scratch:
C:\Windows\SoftwareDistribution
C:\Windows\System32\catroot2
(and Windows Security Essentials was uninstalled, which failed, and I had to run a fixit script from MS. Thanks MS.)
And I think I borked something in the process. Especially since after I "half-assed removed" WSE, the WSUS Offline Updater failed and complained about WSE not being installed correctly. Great. I'm not likely using the offline updater again anyway.
So if I wanted to start this whole thing over again from scratch, I'm assuming that I should do something akin to (again):
1.
Install WSE (and effectively deactivate it via options and just try to forget it's there. I can go through the hell of trying to
uninstall it at some other time).
2.
Do this in an administrator cmd window (from answers.microsoft.com):
net stop wuauserv
net stop bits
net stop cryptsvc
ren %systemroot%\System32\Catroot2 Catroot2.old
ren %systemroot%\SoftwareDistribution SoftwareDistribution.old
net start wuauserv
net start bits
net start cryptsvc
3.
Go into windows update, check for updates, and let it run overnight again.
