Just to close the loop on this part of the discussion:

I don't know very much about the various flavors of "factory reset" for
Windows 10 (using the HP Recovery Manager, in this case)... but looking
through the setupapi.offline.log file, I can see that "sysreset.exe
-continue" and related commands did a bunch of operations with various
device drivers, and then mentioned those drivers again in

  >>>  [Setup PnP Driver Store Property Apply - C:\$WINDOWS.~BT\NewOS\WINDOWS]
and 
  >>>  [Sysprep Specialize Offline - C:\$WINDOWS.~BT\NewOS\Windows]

sections -- and included in that batch of drivers being processed are
mentions of the TAP-Window-related files (tap0901.*/oemvista.inf/
oem43.inf... as well as the drivers for Network hardware devices), 

So, in short, as far as I can figure the "factory reset" which the user
performed did actually involved copying device drivers from the old
installation, including the non-functioning versions of the TAP-Windows
drivers.

It seems like the reset did get rid of some parts of the previous OS
setup (since it cured the system crashes that were happening frequently
beforehand), and it left the system looking "new" (users had to be
created from scratch on the first boot, third-party application were no
longer installed, etc.).  

But it copied just enough of the previous OpenVPN installation that
performing an apparently-from-scratch OpenVPN Windows 10 installer run
resulted in the newly-created "TAP-Windows Adapter V9" device getting
tied to the wrong tap0901.* files....
