This book is all about how to set up the debugger and get some basic information on the error.WinDbg documentation is much much better than this. If you want some good introductory/advanced information about Kernel Debugging try getting hold of DebugFest materials from Microsoft, sells for some $200 as a kit. Thats a wonderful material on Kernel debugging.This book deservs 0 stars. Only this i cant rate as zero. Complete watse of money.
