The GWX control panel is a quick, easy, free program you can download. You can disable the automatic Win 10 update and remove the Win 10 nagware icon.http://ultimateoutsider.com/downloads/
I've used it on several machines and it's great!
I also use this program on my W8.1 Desktop, and my CF-19 which is the only toughbook in my collection that runs W7. Never saw the Get Windows 10 app appear, or boot up my 19 at work and see that hideous W10 UI. GWX control panel works like a charm and I can run Windows Update without fear!
