@ HPY
The deactivation of your AV has been general advice given (for resolving update problems) by MS for many years, which personally I feel is OTT as it could well leave the user vulnerable.

Bear in mind windows 10 updates are delivered automatically as a time and date that is unknown to the user.  Are they expected to just disable there AV on the off chance there might be an update or just around Patch Tuesday.  Even if they only did this for manually updating some of these updates have been known to take a bloody long time (more so if a user has a slow internet connection).

On the topic of disabling your AV, my answer has always been "That all depends".
Normally, my AV is never turned off. When I downloaded the iso file of the current Windows 10 1809 system, the AV was on.
After the download, I check that file with Avast and it was clean as I had expected.
After completing an image backup, and before updating to windows 10 v1809 using the above mentioned iso file,
I turned off my AV and completed my upgrade. IMHO, I didn't need the additional overhead of the AV and any other resident
non Microsoft program on an already system intensive function.

Not as much of an issue if you are doing an off-line ISO update, but not a live on-line update.

Firstly, be sure to have the latest image backup before proceeding.

Secondly, completely uninstall third-party a/v if running Windows 10 and reboot.  Windows Defender should now be active and resident.  Proceed with Windows 10 upgrade with WD as resident.

Thirdly, not possible to not run an a/v in Windows 10 so really this is a trade-off as to how much overhead a third-party a/v presents vs. WD and installing latest version of W10 using the native a/v installed and active.

A smoother install is what I've seen using WD for system upgrades only.  So you can't not have an a/v resident in W10, so a live on-line update is not an issue.  Re-install your third-party when all is running smoothly when done with the on-line update.  Nice to have this option for upgrades.

With regard to turning off or disabling of Security software/anti- virus for Windows Updates.
Interesting, as I have "Never" turned off or had to turn off Avast or other security software before updating Windows even on my XP over the years and have not had conflict or issues receiving or installing Windows updates.

Was "the iso file of the current Windows 10 1809 system" downloaded from here https://www.microsoft.com/en-us/software-download/windows10?
I don't know what an 'iso' file is anyway. Whatever type of file mine was (if did did in fact even complete the download)  it did not upgrade me from 1803--I have just rechecked with 'winver'.

Re the point I made about 'shadowfiles', am I right in assuming that these would disappear with the removal/deletion of old Sys Restore points? That would be good if all traces of my attempt are gone.

The Microsoft site gives you 2 options. The first one is to install the upgrade now.
The second is to create Installation Media. That media is an iso file which can then be burned to a usb or a dvd. Here's the info on an iso file, https://www.howtogeek.com/356714/what-is-an-iso-file-and-how-do-i-open-one/
