OK, I did 3 systems at the other location. Quad processor 8000 Elites.
One I renamed the swsetup directory xxxswsetup.
The others had a subdirectory under swsetup of protectools. I renamed that xxxprotecttools. There were several other subdirectories of swsetup that I did not rename.
I was able to update all 3 by doing this.
The update took a long time, downloading and rebooting several times with updates now occurring that were unable for a long time. Sometimes I had a report that an update failed, I rebooted, repeated the update, and it installed.
These systems were all refurbished ex-business PCs with clean recovery installs by vendors on Ebay. Some came to me as Win 7 machines that I did the free move to W-10 and some may have come as W-10, I don't remember.
Some PC's I built from scratch using HP recovery disks for Windows 7, then upgraded to Windows 10. I don't have issues with others, however, only the 8000 series.
Good luck!

Aha!!
The problem seems to be associated with the HP Protect Tools software package...
One PC that directory was under SWSetup and the other was directly under the C:/
I don't know if uninstalling Protect Tools will fix the issue, but renaming the directory allows updates to occur. Renaming them back may or may not prevent further updates. Time will tell!!
