How can I view Explorer EXE file dependency?

Hi there!
I am having a task that I have to bankroll within a short time if I am to get a bigger assignment. I would like to know how to view Explorer EXE file dependency. I have read over the web but I am not getting any easier way of carrying this out and the clock is ticking. Can someone please help me on this in simple procedure so that I can meet the set deadline. Thanks.
