Those are a lot of questions, so instead of answering them all, allow me to help you another way by "teaching you how to fish". Any question you have, simply go to google.com, and in the search bar type in your question, like "how to setup a new laptop with windows 7", and "how to backup my computer", or "is there a good free word processor program". We can feed you the answers now, but you would still be lost tomorrow when you have more questions. The main difference between someone who can find their way around a computer and those that are lost is that the successful ones can search google and patiently read through the results to find an answer. Along the way you will learn how to use your computer.
Here's a good place to get started that I found by searching google for "free computer tutorials for seniors": http://www.seniorsguidetocomputers.com/
I'm not trying to be mean or condescending , I'm simply trying to help you to help yourself. If you had only asked one question I would have given you a direct answer, but it's obvious that getting some training would help you more in the long run. Enjoy your new computer, pat701.
