I've been getting extremely hacked off with Edge sneakily resetting some of my app defaults (.pdf inparticular). I mean who in their right mind would want to use Edge for anything really? Hmm a "bug" which Microsoft are "aware" of, OK.
Extreme annoyance sorted:

And don't get me started on "Cortana" which now cannot be cleanly disabled and it's insistence on opening an unsolicited, permanent SSL connection to Bing. That's now been sorted here with the quick and dirty folder rename trick. TBH very soon Windows will be gone from everything in this house other than my work laptop.
