Thanks to all for your advice - really appreciated.
In the end I went for what appeared to be the simplest and easiest to use solution which is Never 10. I downloaded Never 10, used it to disable the 10 upgrade, as well as using the 'remove Windows 10 files' function. Couldn't be easier, and to anyone like me who wants to rid their system of this imposition but doesn't have too much pc knowledge, I recommend it. The upgrade to 10 icon has now gone from the right side of the bottom screen bar, and I can relax knowing that my pc won't be changed to another os.
I also took Keager's suggestion and used the windows cleaner to clean my C drive. If there are any further steps I need to take, suggestions would be appreciated. I find it hard to believe that Windows have steamrollered millions of people into something that they obviously didn't want or ask for. It's only by chance that I noticed the 'upgrade' process starting that I managed to avoid it, and saved the hassle of having to change my pc back to 7.
