The TweakGuides Tweaking Companion for Windows 8 is finally available. It covers all of the features of Windows 8, including how to safely optimize and customize most of them. The book is equally handy for new users of Windows 8, as well as those considering upgrading to it. As before, it is available in a free Regular Edition and the paid Deluxe Edition. These guides are well worth a read and offer some invaluable advice. I cannot recommend reading this enough.
