To attempt to address my own problem first I disabled all non-microsoft services in Windows 8.1 professional. When this had no effect on the problem, I then disabled all non-essential Microsoft services. In turn. when this has no effect I disabled all user installed start-up items. Again when this failed to have an impact, I changed my browser from Firefox to Google Chrome, as I noted that the extremely high disk utilisation was at it's worst when using Firefox. This also had no effect.
I then tried a variation of my search on Google "ntoskrnl.exe 100 disk usage windows 8" (I can't remember the exact variation) and stumbled over the above site at the beginning of this message. I had by that point tried everything that was in my power to try. But I noted from this article that the author recommended changing the power plan from 'balanced', to 'high performance'. Since I had exhausted every other avenue, I decided to try this and like magic, instantly it worked. So there is clearly a bug in Windows 8.1 (and 8 prior to this) that causes 100% disk utilisation. I thought someone at MS might like to know about it and come up with a way to fix it.
Below is my system configuration. Please note this system configuration may contain a number of errors, as it was generated with several non-essential Microsoft services disabled. I do not believe these issues need to be addressed. However the issue of 100% disk utilisation when using a 'balanced' power plan on Windows 8.1 (and 8.0) almost certainly does.
PS
This message board system will not allow me to post my full system configuration. MS need a better bug reporting system! Apple allow the public to submit bug reports, so why not Microsoft too. The public can find useful bugs!
