What do I type after x:\windows\system32>?
That really depends on why you are trying to type something.
You may as well have asked "what do I do after I turn left" without any other info.
You need to remember that only a small number of people can read minds and look into your room to see what you are doing on the computer. Most of the world population actually needs to have some information from some source in order to know what is going on.
For example, stand in a coffee shop and stare at the person who makes the coffee without saying a word. You will probably be kicked out before you get what you wanted.
