Thanks for letting us know.
When you run the
"winver" command, do you get b1607;v14393.10??
If you did, that's the latest version from today's update. Haven't seen a solution to that, but give us a couple of days. In the meantime, you might consider
"rolling back" your system using built-in windows
SYSTEM RESTORE utility, and try it again. Make sure that you have any and all extra storage drives (both internal and USB) disconnected from your computer's Motherboard prior to letting the update run again. Also, disconnect any and all USB peripherals such as external hard drives, flash drives, printers, scanners, webcams, UPSes, etc. before re-running the upgrade again.
Only 1-W10 machine I have out of 5 updated today; and I did not run into your problem.
'luck!
