More Windows 10 annoyances

I have been putting off the Windows 10 upgrade on my main laptop and now Microsoft is getting more annoying.  I would like to turn off the 'notice', but, I haven't see any option.  More annoying is they pop up their notice over top of whatever I am working in.  I was lucky in that I wasn't doing anything dangerous in the online game, but, this is something that should not be done for advertising an upgrade.
