FINAL UPDATE
I paused before restarting the 564th update from 16193.1001 to 16241.1001 and looked to see what, if any, drivers might be missing or changed. Looking in....
C:$WINDOWS.~BT\NewOS\Windows\System32\drivers directory and compared those found in the 16393.1001 C:\Windows\System32\drivers
No sign of the following files being migrated from 16193.1001 to 16241.1001 - perhaps intentionally dropped or possibly the two nv*.* files are to be replaced/updated?
- ASACPI.sys
- HdAudio.sys
- nvhda64v.sys
- nvmf6264.sys
- srv.sys
While many had changed in size a number of new files were found - perhaps the two nv*.* are the replacements?
- bttflt.sys
- invdimm.sys
- ipt.sys
- mshwnclx.sys
- nvdimmn.sys
- pnpmem.sys
- ramdisk.sys
- rteth.sys
- vnvdimm.sys
- wdnsfltr.sys
I also looked into the C:$WINDOWS.~BT\NewOS\Windows\System32\DriverStore*FileRepository**and again compared what I found there with what I found in C:\Windows\System32\DriverStore*FileRepository ....
No sign of the following being migrated from 16193.1001 to 16241.1001 - perhaps intentionally dropped or possibly the six nv*.* files (I've yet to confirm that they are all Nvidia drivers) are to be replaced/updated?

While new drivers were found - perhaps the invdimm.inf or the vnvdimm.inf is the replacement? - possibly misnamed?

Anyway, copying the files and directories from C:\Windows into the corresponding locations in C:$WINDOWS.~BT
didn't help the upgrade complete but it did screw up the LAN drivers when it eventually, after another restart, booted back into build 16193. Hey I didn't think it would work either but it was worth a try! :)
I might just try once more removing the first character of the nvdimm.inf files just for **** and giggles.
That said, I doubt that'll work either so this will be my last update on the topic unless it does work or I find another solution but, for now, I think I've gone as far as I can so back to 15063.481 and wait to see what happen when the Fall update arrives......
Thanks to everyone for their suggestions and assistance but it's now over to Microsoft!
Cheers
