ok so I got this little windows icon in my systray now. offering me an upgrade to 10 .What I have read elsewhere and from Microsoft is that if you are running a legal copy of Win 7 or 8 or 8.1 it is a free upgrade to Win 10 and you have a year to install it - no other strings attached. long as as its an opt. I have 7 and it works just fine and im gonna keep it.
I bought a used back up PC with 8.1 and it runs like crap. really slow. so i may try 10 on that one. I think maybe MS is offering a way out of these 8 versions myself. most people don't like em IMO.
