I have the same problem, and as previous people have said it seems every time a Win10 update is installed, all the old problems seem to re-appear...….along with a load of NEW problems which come from nowhere.
It is high time Win 10 was sorted out, it seemed so good AT FIRST them the problems started with the ad-hoc updates which occur randomly.
I'm afraid if this persists I will be another candidate for APPLE MAC.
