But after a Reset this poster TwoPuddies  found a way to solve the unable to update problem.

Hey Mr Bill Smithers,

Juts to give an update: I didn't actually try to reinstall Windows. Instead I procrastinated for a while then decided to go looking for a solution again that didn't involve reinstalling Windows, prior to giving up and then reinstalling. Ha!

I'm not sure how I found it but I found someone else having the same problem with a Lenovo laptop who had found a solution after posting on another forum (I posted here and Lenovo forums). I hope I'm not breaking rules by posting links to external websites (my apologies if I am) but here goes:-

https://www.bleepingcomputer.com/forums/t/635451/win-81-reinstalled-now-have-problems/

The link says if KB3173424 doesn't solve the problem (this is the KB file the link you posted to the Fix Windows Update issues tells people to download as part of the troubleshooting process) then download the July 2016 rollup which is KB3172614 - which is dependent upon having KB2919355 and KB3021910 installed.

The machine I was having trouble with had only KB2919355 installed but I thought I'd try installing KB3173424 anyway, and as soon as it had installed and rebooted the machine I had 227 updates waiting for me. Woo!!!
