If you need the bare minimum...
There is two sides to this book. In one respect it is not nearly as comprehensive as it should be, in the other, it is ideal for someone who knows nothing about computers. Windows Professional for Dummies takes you through the bare minimum of features on a step-by-step basis. The advantage of this is that you don't have to be a genius to use the book, but the disadvantage is that you don't get as much out of the book as you would have liked. When my father first started using a PC he knew nothing about it and this book was a great start for him. I am impressed by my father's progress since he received this book, but I realize that most of his progress was through trial and error, not through this book. If you have to learn how to click a mouse, this book is great, if you want to be able to do more, I would recommend you look for another book.
