I don't know if this helps, but the notes below worked the first time with both 1703 and 1709 updates.

I hope someone gets to see this as this is a surefire way to install major Windows 10 System Updates. I've
tried all other standard ways and none work. Below is a process that worked the first time with Version 1703 and 1709.
You will need to have capability to do the following first:
1. Your PC has to have the capability to be set to BOOT from DVD drive or Flash Drive.
2. You need to download the latest Win 10 ISO file.
3. You need to install the ISO file on a new DVD disk.
4. You should have your PC System backed on an external device and a way to boot
your PC to the backup medium to reinstall your old system in case of disasters.
I used Paragon B&R and could boot my system from a DVD with Win PE to restore.
5. You should know how to use CHKDSK /r to fix hard drive problems. I had to do this.
6. The Win 10 installation goes quickly. You will be asked to supply a number of ID's
and Passwords which I assume (if your reading this) you already have!
7. During the installation you will be asked for your Network Name and Password.
I did not supply as I wanted access to MS Office installation and rebuild of PST files
before Outlook started to down latest E-mails.
8. One final note before actual installation, This install does not automatically save
Your applications and folders. However, the install will create a new file -
c:\Windows.old which is a capture of your old system. You can populate all the files you
need from this Windows.old folder. You will have to reinstall your apps.
9.
Now on to the installation.
10. Place your ISO file or ISO Flash Drive in appropriate device and power up/restart
and activate the BOOT from DVD/Flash Drive as appropriate. On my PC I used
the space bar (really any key) to force BOOT from the DVD drive.
11. The install process begins and various screens come up with standard answers
required.
12. On Windows Setup screen select "Install Now". Select "No Key" on screen that
asks for Windows key. On Select OS Screen, select Windows 10 Home. On What
Type Install screen select "Custom". On the where to install screen
I used "Drive 0, Partition 2 HP" to force install to C:"
Other screens should be obvious!
13. Lucky 13! The rest of the install continues to completion. A number of
reboots will occur and finally your install should be complete.
14. I know this has been a long discussion and I hope I didn't miss something
important. Good Luck!
