Welcome aboard, Norcot.
You understand that we don't work for Microsoft, and Microsoft is not responsible for anything that we say on this forum.
Having said that, MS has decided that it is to the benefit of everyone to have a single operating system, which they will control. They really believe that.
To be fair, you have part of this already. Google and Yahoo are cloud-based software that are updated without asking the users. And they both work well.
MS made Windows 10 a recommended download, which you have agreed to accept. Yes, you can keep on refusing it. After July 29, MS will stop nagging you to upgrade.
