The Microsoft Press Windows XP Professional Resource Kit/Free Chapter Troubleshooting Windows XP Startup Here has a very helpful 10 section Appendix that is probably worth the price of this book and a book in itself with sections that are directly useful for trouble shooting and understanding the everyday tools in XP explained in more depth than many of the fat XP books available. The second edition has two extra security chapters and some added, emphasis on the CD on Windows 2003, but I noticed that many sections in the Appendix had been rewritten with more understanding and depth. Definitely one of the most helpful XP books to help you understand how to get out of trouble because of this appendix.
