Thanks for the post Kingfish.
I don't generally mind Windows performing updates one my PC. The options in the link you sent all seem to stop ALL driver updates etc. I am just trying to find out what version of the AMD Display Adapter I am best using (and why the one Windows installed appears to be a newer version).
I am using Windows 10 Home so I don't think some of the options to stop updates are possible on my system. I have already set Windows to not 'Automatically download manufacturers' apps and custom items' etc but that doesn't seem to block the driver updates.
If I need to I will try the Microsoft 'Hide Update' tool to see if that will roll back to the drivers I want.
