If you want to get rid of the windows 10 upgrade nag I found this program called Windows 10 When I Want it.  I have run it against every a/v engine i can think of and it has not tripped my own defenses so it is as good as i can test it to be.  It DOES remove the wind 10 nag and remove the files Microsoft has forcibly foisted onto your machine.  If you do NOT want to upgrade to windows 10 run this program..:)
