I can sympathize with you, for me win10 is a fail on many levels.
Some here believe it to be a wonderful OS, I don't see it, for me
I am now getting this hot mail pop up, it's a PITA, but when it disappears mail will not load at all, no win or hot mail, go figure.
I can see having one or 2 quick fix glitches, but it seems they were more interested in their new SPYWARE the a good OS.
We can probably chase this back some were to BOZO, our clown & chief.
