This book has been at my right hand for a month while I have been switching from Windows 98SE to XP. I could not have installed XP without it. I've used Windows 95, 98 and 98SE, but XP is enough different that a book like this is absolutely needed. The book has checklists for before and after installation and extensive explanations for "Using Windows" once you are up and running. The technical level is about right for me now; later, I will want more depth. The accompanying CD and the Tour that comes with Windows will help the rank beginner.
I am not on a network so cannot critique the network chapter.
And a remarkable plus: I had a question about getting out of my multibooting configuration, and the authors answered me on-line with carefully thought out advice.
Yes, the book has some gaps: it answered about 80% of my questions, so I give it 4 stars.
Don't install XP without a book like this.
