Windows XP Performance Tweaking Guide Updated "This guide has seen MANY revisions since it's original posting more than 3 years ago. Even after all this time I continue to add to this guide and revise it as needed. Please read this title very carefully because this guide is ONLY intended for Performance related tweaks. There's millions of other "tweaks" that other guides use but have nothing to do with performance. In this guide I'm ONLY including what actually has some kind of affect on performance. I am trying to keep this guide dedicated to tweaks that directly affect your performance. I've also started working on a tweaking guide for the paranoid which can be found here. I'll be creating a customization guide and also a more detailed/serious security tweaking guide whenever I find the time."
