While most Windows books concentrate on a ground floor approach, Platinum Edition Using Microsoft Windows XP takes an entirely different approach - one that assumes the reader is a bona fide Windows black belt who wants or needs to manage multiple users in a networked environment, turbocharge a Windows installation with registry tweaks or stop hackers in their tracks. This book doesn't waste time telling the reader how to simply live with Windows - it tells the user how to squeeze every last drop of performance from it.
