The fix is for the problem that was showing in 'Radeon Settings Advisor'
So your still getting the notification in the section I've arrowed ?, then use the 'Report Issue Online'.
It's not about older as such but the last signed driver by MS which is recommended - well, just disable Notifications to stop that.
the point is that if you load that last driver it will then tell you to load the latest driver you just uninstalled. Yes it is easy to ignore. But novice user get highly confused by this and think they are doing something wrong and keep following the so called recommended advice. AMD lists this issue as fixed and it clearly is not fixed.
