Thank you for the detailed response.
It's really funny, I like windows 10 a lot, for me it's the best Linux distribution, but there are a few of these little things...
To reply to some of your points to clean up possible misunderstandings:
> If you initiate a Copy and then change focus, the dialog will not steal focus. Perhaps that's what you're experiencing?
No, I drag or Ctrl-C/V file between two explorer windows and a new window icon appears on a taskbar with progress indication (by a backgound color fill), but the progress window is not visible until I click on that icon or Alt-tab to it. There are some complains and workarounds about this on the web.
> That notification sits in the tray until you manually dismiss it.
That is the cause of the problem for me. The notice is mostly invisible (no dialogs), until 7 days later "You have 15 minutes to pack up your things"...
> If you've installed a driver directly from the Vendor, Windows will not supersede that install with the Windows Update Version
It absolutely does. I manually install 341.81, everything works. Then, some weeks later bam, black screen, driver crashed. And a notification that driver was updated. Same way touchpad driver keeps updating after I manually reinstall it.

See search results for "An App Default was Reset"
Since the amount of side-effects from the combinations of installed 3rd party software (antiviruses, ugh) is so huge, I'm constantly amazed they keep everything working and backwards compatible as much as they do. But some of this new stuff, eh.
