According to M$, their AI is solving problems at a rate no human is capable of right now, at this very moment. (Or so they're telling me constantly in their ad campaign on network TV). Maybe they should give their engineers a rest, and let AI fix these oft appearing glitches. Here;s the thing though, if we listen to your story, those issues should only be appearing in Windows 10, for the reasons you outlined. While the "issue du jour", is indeed with Windows 10, the last one was with an update which trashed Windows 7 machines, running after market AV solutions.. \ You don't have to be much of a conspiracy theorist, to know that M$ wants Win 7 off the street, and Windows 10 in its place. If only for the simple reason that Windows 10, herds you to the M$ store. Accordingly, one has to wonder if the damage done to Win 7 installations with updates, isn't intentional, not employee complacency, nor a not so bright AI. Now M$ security Solutions and Windows Defender were little more than vapor ware in Win 7, but all of a sudden, they're rated at the top of the heap, as long as you're talking about Windows 10..
