The new versions of the TweakGuides Tweaking Companions (TGTC) for both XP and Vista are now available. All versions of the TGTC, both the Regular and Deluxe Editions, e-book and hardcopy, have been updated. This is a reasonably major update given the last time the Companions were revised was over 6 months ago. The most significant change is the Internet Explorer chapter which has been completely updated for Internet Explorer 8, however there are a range of other changes as well. Note that although a Windows 7 version of the TGTC is not yet out - and hopefully will be released if I am able to devote the time to it - for now Windows 7 users can utilize the TGTC for Vista as most of it applies to Windows 7 as well.
