Upgrade to Win 8.1 Pro using an ISO download
So far I have been able to upgrade computers running Win 8 Pro to Win 8.1 Pro using the in-place method via the Store.
This is a highly time consuming and inefficient method, requiring some 3 GB of download each time.
Following the suggestion of some, I downloaded the Win 8.1 ISO from the following site;
http://windows.microsoft.com/en-us/windows-8/upgrade-product-key-only
However, using it requires an 8.1 product key to work.
My question is the download from the Store has to be placed somewhere in the computer prior to the updating process. Somewhere in the software distribution folder I guess.
Is there a way to get hold of this download before the actual updating commences?
(Presumably, the download gets either modified or removed following completion of the updating process.) And if so, whether this download could be re-utilised on another computer?
I am not holding my breath on this one. But I am confident that there will be an Expert who has found a way to do it.
Would be great if I get an answer to this one. Thanks

Just a data point: Upgraded to 8.1 using McKnife's process above and mounting the ISO file (using Windows Explorer) and double clicking the setup file as mentioned above by rindi .
After upgrading IPv6 related protocols using Microsoft Update (because the Internet connection kept dropping) everything runs smoothly.

Thanks for the very useful suggestions, Experts.
More encouraging than I had hoped for.
I think I have enough at this point to run a trial of both McKnife's and rindi's approaches.
Should be able to revert with conclusions in the next couple of days.
Meanwhile, thanks again.

I have now been able to carry out 2 separate upgradings.
Brilliant!
Both approaches worked without a hitch.
Thanks for coming to the rescue.
I am very grateful indeed.

Or you can extract the contents of the iso to a folder on your PC and then start the upgrade process from there by starting the exe file (probably setup.exe).
Or you can put it on a USB stick from which you can then boot the PC or run the setup process from, using the following steps:
