Windows XP Tweaking Guide

This was the first comprehensive, step-by-step XP tweaking guide on the net. It's over 3 years old and continues to evolve. I started working with XP during its RC1 stage. After a time I began looking for ways to tweak it. I haven't "invented" any of these tweaks. They were scattered all over the web, a couple at one site, a few more at another. Some were good and as I discovered over time, some were bad. What I have done here is to investigate/test them, try and organize them in a coherent manner, and present them in a step-by-step guide.
