Initially upgraded from Windows 8.1 to Windows 10 RTM, I'm using Windows 10 Insider Preview (aka "Fast Ring") for approx. half a year now.
Currently, it seems to be way too unstable to me.
Therefore I want to use the "regular" Windows 10 again.
Everything I found so far was this Microsoft article which basically boils down to using a recovery image.
My idea was something easier like e.g. just installing Windows 10 over my current Insider Preview to keep my settings and the like.
My question is:
What is the recommended way of downgrading from Insider Preview to RTM of Windows 10 while (preferably) keeping my settings?
I've ended setting up a new Windows 10.
