I feel that I have to say that my SB is now working perfectly. Over the last two months I have experienced almost all of all the issues ever raised in this Forum, and I only have one left: the Flight Mode indicator in the Notification Panel is often highlighted as ON when it should show OFF. And that is trivial, and probably a pure Win 10 issue. I have religiously applied the updates ASAP, but I'm sure everyone does that. I am beginning to think that the Windows 10 DISM restorehealth process from a Win 10 image file (described elsewhere) is the thing that has performed this magic trick. How many others here have tried it?
