Tweaking Companion logo

The TweakGuides Tweaking Companion (TGTC) is the complete system customization and optimization guide for all Windows users. Designed for novice and advanced users alike, it is written in plain English to help you genuinely understand all key aspects of Windows and your PC. The guide covers every major topic, from the correct installation of critical drivers and software, through to simple explanations and recommendations for every significant Windows setting and feature, all the major performance and convenience tweaks and customizations, as well as detailed troubleshooting advice. Also provided are links and instructions for a large number of reliable free applications that can enhance your system and give you viable alternatives to purchasing commercial software.

AUGUST 2019 UPDATE: Given it's been some time since the TGTC was updated, and sales of the Deluxe Edition have dwindled into insignificance, I've decided to release the full Deluxe Editions of these books for free, and you are welcome to redistribute them however you wish (HTTP, FTP, Torrent, etc.). The Windows 8 version in particular still contains a great deal of potentially useful information for users of both Windows 8 and Windows 10. To further maximize their possible usefulness, I've made their contents available under a CC BY 4.0 License (see further below). This means that you can modify and redistribute them, even for commercial purposes, as long as you provide clear attribution and indicate the changes made. Thank you to all of the people who generously purchased a copy of the Deluxe Edition, your support helped to ensure the survival of this site during difficult times.

Windows 10

A TweakGuides Tweaking Companion for Windows 10 will not be released as explained here. Aside from interface changes, Windows 10 is largely similar to Windows 8.1 in terms of features and tweaks, so I recommend that you use the TGTC for Windows 8, combined with the Windows-10 specific tips and tweaks starting on Page 12 of the Hardware Confusion 2019 article.
