Ok if you're not joking in your first post, you should not be using a computer. Secondly, If you have to ask the types of questions like you did above, I'm curious as to how you even got to this forum (again, still assuming you're being serious).
If you really are just joking, a quick Google search should revel a few hundred or so install guides for Windows 7. They should tell you everything you need to know.
