There is some good info in this book (especially on COM, DAO, and RDO), but the overall presentation is verbose, frequently disorganized, and ultimately ineffective as a WinArch exam study guide. Far too many pages are spent on personal opinions, Microsoft bashing, off-subject material, and reference-style lists of interfaces, objects, etc... If the author intended to write a reference book on Windows Architecture, then the title and advertising for this book should reflect that. Watch out for the section on Microsoft Solutions Framework: the author claims it gives you enough info to answer exam questions, but it doesn't cover three out of the six MSF models.
