This is just an idea, but if you don't have considerable data and time tied up into what's going on with your updates right now and you have plenty of Bonus Bytes data and the time, you might want to look into downloading a new copy of Windows 8.1 from Microsoft and performing a fresh install with that (if it's different from whta they did with the remote session). When I was having all of the problems with my Windows 8.1 updates and installed the freshly downloaded copy it worked very well, though I had to install two files (one required prerequisites) after the fresh OS installation in order to be able to perform normal updates, but they were just the June 2016 Update Client and the July 2016 Update Rollup (and the prerequisites for the latter). Once those were installed the updates went perfectly.
I can't guarantee that this will solve your update problems and such, but it may help. Of course, again, this takes more data and more time, unfortunately.
