I skimmed this one, skipping entire chapters I knew I wouldn't need anything from, but I still managed to learn a few things I haven't encountered in other books yet. My favorite tip was how to make the Start screen show the desktop background. I really liked the organization of this book. It is pretty thick, but it's easy to find what you want to learn more about.
Not a "summer read" kind of book. I've moved this one to the reference shelf. I was immediately able to find what I needed to get around in Windows 8, and will keep the other 800 pages around for when I need them.
