What is the TweakGuides Tweaking Companion?
The TweakGuides Tweaking Companion is the complete system optimization guide for Windows XP users. No longer do you have to put up with so-called "Windows XP Guides" which have a handful of Registry tweaks and some vague optimization advice - the TweakGuides Tweaking Companion brings an enormous range of detailed descriptions and resources together in one free 170 page downloadable PDF file. Everything from the correct installation of Windows and critical software and drivers, through to recommendations for every significant setting in XP, all the major performance, visual and convenience tweaks, and descriptions of XP's functionality. The guide includes comprehensive chapters on overclocking, benchmarking and stress testing, troubleshooting and regular maintenance procedures. Basically the TweakGuides Tweaking Companion is the mother of all Windows XP tweak guides and system optimization guides.
Note: This guide was formerly called 'The Windows XP Tweaking Companion' (XPTC). The content remains exactly the same, however the name has been changed due to legal action by Microsoft.
