This book is an incredible job by the author who is obviously talented at presenting the incredible amount of data necessary to do ALMOST anything with Windows at the script level. I rated it 5 stars because if you are trying to write Windows scripts, this is a good place to get started. The issue I have, however, is with the topic and Windows. Windows and most applications that run on it are really not set up for scripting, and that especially includes the obvious programs like OneNote that need it the most. Therefore don't expect an easy solution to a complex problem.
Windows suffers from an ill conceived and poorly implemented operating system architecture held together with a rats nest of bandaids and timeouts, and these are your true enemy. Scripting can't fix this problem, its built in. For example, you can print a PDF file to onenote but how do you tell when OneNote is ready for the next sequential print job so that the documents are stored in order in your notebook? You can't. All you can do is code time delays and hope that the machine always completes its task before your timeout sends it more data. If you really want to expand your control over windows, you can also use autohotkey which will inject keys, allow you to program time delays, and permit you to control the active window and sense when it changes.
The beauty of WSH is the architectural split between the various language interpreters you can use or install (like perl, python, etc) and the management of the scripts and additional functionality it exposes. This is nice, but most (if not all) of that functionality is already exposed in libraries and components for most scripting languages anyway. Its just nicer having it all in one place and documented, hopefully in a way that maintains consistency in the future as the OS evolves. (not likely though)
So if you think you want to develop some scripts for Windows, this is a resource you do need, but don't get involved in trying to make your Windows machine into a computer. Windows is designed as a single user, multiple application environment that relies on the fact that you can't press keys very fast. If you do, applications will bleed memory, crash, and sometimes even Windows will crash. The buffers, the handshaking, the gui response are simply not appropriate for high performance application utilization in Windows. If you need that, use Linux which is a multiuser, multiapplication system from the ground up. It suffers however from a dearth of applications like MS Office 2010, OneNote, Acrobat, etc. If you are a generic user, there are open source apps that will do most of what you need, and the good news is they are probably free. In Linux the applications must assume that they don't have the entire machine, they can't use timeouts, and they generally have very sophisticated command line interfaces, with bidirectional information flow to support scripting in a high performance multiuser environment.
So why did I buy this book, if I'm a linux guy? Well, so far most of you are still using Windows, and that means I need to be able to deliver solutions such as they are, to people who don't know what computing can really be like! To that end, this book is a well organized manual, reference tool, and its commentary is quite frank and honest. The author admits, for example, that programming a Windows application using keyboard insertions is a "nightmare". He's obviously done it, and those of us who have wake up screaming on occasion when we remember what it takes to make sense out of the response of a Windows application to real world heavy duty problems.
The bottom line is that WSH is not going to turn Windows into Linux. It's not going to make your applications respond in a predictable and timely manner or avoid the numerous shortcomings of Windows when it comes to handling large and repetitive tasks (like memory bleeding). It will give you a platform upon which you can develop some standardized, supportable, modern, scripts using your favorite language and up to date objects for your version of the operating system. So set your expectations accordingly and buy this book. Its far better than most books relating to Windows in terms of content delivery, and if you are still writing .bat scripts, you will benefit immensely. Things have changed dramatically since those days!
