Learning my new computer

Just got a new Windows 10 computer and am trying to figure it all out.  It's sure different from what I've been using!  I still have no clue on how to set up favorites, get icons onto the desktop, etc.  When I tried to type in the address for this blog, I got a message saying I couldn't access it because of the security certificate.  But, when I searched for it using the identical URL, I wound up here and was able to type in this post!
