I actually bought this book by mistake while browsing and didn't realize it until a week later. Considering the price I kept it. What you'll find in here are a collection of useful fixes for problems that pop up for the home user. Yeah, you can Google it and find 186,419 so called fixes, but perhaps 10% of those are really applicable to your problem. The book is a bit dated, even to the point of Vista users upgrading to Windows 7, but, like XP users, there are probably tons of people still preparing to do just that now.
In my opinion, Windows 7 is the best operating system Microsoft has published todate, and will most likely be a system a lot of folks (especially desktop users) will hang on to, dispite all the hype from Microsoft to switch to Windows 8. My advice is to start at the beginning of the book (unless you are really Windows savy) and read through to discover all the things you didn't know about Win 7.
At the same time, you will run across little glitches and problems you have but have been living with, because you didn't know how to fix them. That's what this book is...a small handbook to keep your Windows up and running at peak efficiency without having to hunt and search for the answer to your problem. It is well worth the price for the electronic version. DO the routine maintenance suggested and you will avoid many of the problems you have now before making your system well and thriving. Have fun!
