The task manager showed 43 pages of listings of update tasks with a windows network connection, but you are correct that they all had the same PID.
Before this, the computer was literally choked out with CompatTelRunner.exe running, which I referred to as "more than one thousand" as they were averaging about 32K bytes each and collectively the load on the hard drive was 100%. But I suppose it was quite a few less than that.
Also, this is my Windows 10 computer, forgot I switched it with a different one.
I had turned off the windows 10 update service, by configuring the service to disabled, and the group policy was not set, but it somehow turned itself back on.
The 43 pages refers to the image. I paged down 43 times to get to the end. This was when things were a bit better, so I was able to do this.
