After another two startups everything seems to be back to normal - meaning: no more prompts for every normal Windows function / open event viewer or services. And the ones that usually should prompt are blue again.
So - I think the culprit is one tweak in the Pro Version - in performance tweaks.
I will leave it alone, all reset by Windows Tool ... maybe try to locate it, by checking out,one at a time, certain performance tweaks and see if it comes back
Cheers
