About this book

Before PowerShell, I began my career as an IT Pro, pointing and clicking in the GUI. I wrote this book to save IT Pros from themselves by reducing the learning curve and helping them avoid being reluctant to learn PowerShell.

Instead of a book that covers topics with fictitious scenarios, this book is a condensed version targeting the specific topics that an IT Pro needs to know to succeed with PowerShell in a real-world production environment. It's a collection of what I wish someone had told me when I started learning PowerShell. I include tips, tricks, and best practices that I learned while using PowerShell since 2007.

Each chapter includes a curated collection of links to specific help articles that expand on the information covered. These resources expand on the concepts discussed and broaden your understanding of PowerShell.

Who is this book for?

This book is for anyone wanting to learn PowerShell. Whether you're a beginner or an experienced user, this book helps you improve your PowerShell skills.

This book focuses on Windows PowerShell version 5.1 running on Windows 11 and Windows Server 2022 in a Microsoft Active Directory domain environment. However, the basic concepts apply to all versions of PowerShell running on any supported platform.

Lab environment

The examples in this book were created and tested on Windows 11 and Windows Server 2022 operating systems, using Windows PowerShell version 5.1. If you're running a different operating system or version of PowerShell, your results might vary from the ones presented in this book.
