Well, I bit the bullet and downloaded the free Windows 10. It only took about 24 hours to finish! Then I selected Customized Installation and got rid of all the "call home" stuff. I have not yet done the other stuff, but I already like Windows 10 much better than 8.1, except for one problem. I cannot reply to my Windows Live mail. It gives me error messages. Meanwhile, I get notices that I need to download NET Framework 3.5 to get an app to work, but doesn't name the app. So I go on the Internet and find out that I need to go to Control Panel > Programs > Turn Windows features on or off >Dot the option: NET Framework 3.5 (includes NET 2 & 3). I go there and do that AND un-dot the NET Framework 4.6. Advanced Services version below it. It moves to "Downloading" and quickly fills the green indicator. Then nothing else happens. I repeat, this time keeping both versions checked, but that won't work either--not surprising. Now I'm between a rock and a hard place. Anyone got words of wisdom for me?
