Apart from the hard work put into researching and writing, the realization of this book would not have been possible without my publisher Packt Publishing, and the efforts of their Acquisition Editor, the team of Technical Editors, and Proof Readers in helping to complete the book. I would like to express my appreciation and gratitude to the Project Coordinator, Kranti Berde, and the Lead Technical Editor, Ankita Shashi, for their contribution and guidance.

Moreover, I wish to acknowledge Microsoft Lebanon for providing me with the opportunity of delivering training sessions on Windows 8, which contributed to my experience on the subject matter. I would like to express my gratitude for my friend and creative UI designer Michel Makhoul for his work on the cover image. I also wish to express my appreciation for the people who supported me throughout this journey, namely, my colleague Chukri Soueidi for providing me with technical advice and encouragement and my technical mentor Firas Hamdan for his contribution to my knowledge and professional advice.

I would also like to take this opportunity to thank my family who supported my efforts while writing the book.

Above all, I want to express my appreciation and to thank my loved one Elissar Mezher for believing in me, supporting and ever motivating me, and mostly for understanding my long nights at work. Thank you.
