I thought this book was going to be full of things Microsoft don't tell you such as hints and tips. But no, its stuff they don't tell you because most of it is insanely obvious. Like minimising and maximising or adding a Printer. Microsoft are probably just saving paper by not printing this sort of stuff. If you're a complete newbie to Windows buy it. If you're looking for stuff they don't tell you, like (well I'm not sure now because I didnt find it here!).
This book will NOT make you and XP expert. At best it might save you from embarrasment.
