Dear Johann Eva:
Would it not be lovely ... go to Cortana, hum I can't :-(!
Since the Fall Creator's update, I have lost the use of Cortana (which I don't use generally), the keyboard's Windows key (on its own) does not bring up the start menu nor can I bring it up with my mouse! I also can't sort out the settings on my keyboard or mouse (both Logitech). I obviously can't shut down or restart from the Start menu (see above) I also can't pin programs on the Taskbar. Just to add to the pleasure, I can't start Edge either.
Oh ... it appears I have a blank Recovery area. So forget 'rollback'. Do I 'really' want to go back to total system reinstall? You have three guesses ...
Back to what I'm answering to: you wanted some feedback! Will this do?
The PC is working in a fashion.
God grant me the patience and forbearance to not do 'anything' stupid that will make it unworkable.
