7 Home Premium in-place setup cancels itself, cannot sfc nor wupdate

Yeah, that would be a copy not an extraction. The instruction makes no sense at all to me.

No, just unzip the Update7v4 files to C and run the .exe as Admin.

Have the Updates in a file in C so it will find them easily when prompted to show location. You can change the destination in the Updater's dropdown.

I use that installer for all of my installs without having to do any more than 2 or 3 Updates lasting 5 minutes.

When you have the Update7v4 file extracted to C and run it's .exe it will ask you for the folder location of the Updates you've downloaded, and for the Win7 installer files which you've also extracted into their own folder. You'll then choose your licensed version and it should run.

So these are three separate functions which once each is complete are knitted together by running the Update7v4 .exe from within its folder. It starts a script that does the work for you from there.

Sounds like a timesaver. To construct it however I just let it go build itself for a couple of hours, and it appeared quite busy but seems not to have done anything.

Now I can't figure out whether the changes made to install.wim before it went into permanent hang have rendered my setup files useless.

It shows you the progress as you run Updater7. Did it find the Updates and ISO files? Watch its progress, have it make an ISO or just drag the files it's updated onto the stick if you've already formatted it to replace the ones there now.

It took around four hours but did allow me to save and burn an ISO; I just have no idea whether it's a valid installation package and whether my UEFI will allow it to reboot/reload itself to successful completion if so - also, whether there's any way to avoid destroying the manufacturer's recovery partition.

I cannot imagine it taking that long until I scroll back up and remember the condition of your OS.

So boot the DVD and see: UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums

I have no idea how to interpret the difference(s) - if any - between Option/Step #2 and Option/Step #3. I appear to have a bootable DVD on a UEFI/USB DVD-R drive. Is that bad?

What are you talking about? I just gave you a tutorial to install in UEFI mode. So boot the disk and install. If you are booting a DVD use the option for booting a DVD. The other one is for booting a flash stick.
