Windows 10 was installed by Microsoft. I had Win 7 and was contacted by them that I was inline to get the initial download and did I want it? I agreed and when it was announced they were sending out win 10 I received it. It works fine, has all kinds of stuff I do not need or want like apps and cortana, who needs their computer to talk to them?
My only complaint is that I get very few windows updates, same with win 7; so I don't know if I have enough security.
Thank you for answering my questions.
Is Emsisoft different from Windows Defender and Webroot or the same? I never know if I'm using too many of these programs.
