UPDATE:
I made a System Image and ran Dism /Online /Cleanup-Image /RestoreHealth /Source /LimitAccess from the original uncustomised ISO. It took about 4 minutes and completed successfully!
I had a quick look and it seems OK. I will investigate further at some stage.
One interesting thing. When I ran Dism /Online /Cleanup-Image /RestoreHealth previously, prior to using the original ISO, I got the error . .. .
After using the source wim, I ran the above again and the online RestoreHealth worked first time.Deployment Image Servicing and Management tool

I have now re-imaged the OS back and I will investigate more in the week!
