I am a senior citizen and am thoroughly confused with all the changes with Microsoft and its various programs.  I was told Windows Live will no longer exist and that I must use Outlook.com.  I signed into this by have no idea as how to get into it - is there a shortcut that I can put on the Taskbar?  

Now I am concerned that Microsoft Security Essentials will be discontinued, if so, what can I use to replace it? 

I also keep getting a reminder to upgrade by computer from Windows 7 to Windows 10.  At this stage in life I do not look forward to trying to learn a whole new technical program as I am finding that these get more complicated and harder to understand.  Why can't I keep using my Windows 7?

I liked Microsoft years ago as I was able to get a computer at a reasonable price and found working it not that hard, but, as time goes on your products get more complicated and harder to operate and understand.  I realize the world is changing and understand the need for updating, however, is there not a place for those of us who do not have multiple gadgets and have smart phones etc.  I have no need for these items?  Just wish someone out there would listen!
