PowerShell 7 for IT Pros

A Guide to Using PowerShell 7 to Manage Windows® Systems

Thomas Lee

Foreword

Ten years after the release of Windows PowerShell 1.0, the PowerShell team announced PowerShell Core 6. The work toward PowerShell Core 6 started a few years earlier, and that was when I became the engineering manager for PowerShell. It was not easy early on, particularly in terms of compatibility with Windows PowerShell, but with the PowerShell 7 release we are officially starting a new chapter for PowerShell in which PowerShell 7 can be used as a replacement for (or side by side with) Windows PowerShell 5.1.

PowerShell 7 represents the future of PowerShell based on three big changes:

A single automation language for Windows, Linux, and macOS:

Windows PowerShell has been heavily adopted by the Windows community. With IT moving toward the cloud, this presented an opportunity for PowerShell to be the glue language for the cloud. Improvements to the web cmdlets make it simple to call REST APIs. Early partnerships with Azure, Amazon Web Services, Google Compute Cloud, and VMware ensured PowerShell cmdlet coverage for any cloud you would want to use on any platform. Along the way, we also made PowerShell a great shell to use whether you are using Windows, Linux, or macOS.

Moving to open source:

This was a huge change in how we write software and also how we engage with the community. We could now be much more transparent with our plans and also accept contributions from the community to address issues or add features that would not have necessarily been a priority for the team. With about 50 percent of the pull requests coming from the community, PowerShell's future really is a community‐driven project!

Early adopter of .NET Core:

It was not without challenges that we moved from .NET Framework to .NET Core (and now just .NET). Compatibility with Windows PowerShell modules was the biggest issue initially. .NET has come a long way in addressing the compatibility gap, adding back many APIs to enable PowerShell to be compatible with existing modules. In addition, .NET Core has substantial performance improvements that make existing PowerShell scripts and modules simply work faster without any modifications!

The mission statement of PowerShell is to make it easier for users to use compute resources. With PowerShell 7, this includes different platforms such as Windows, Linux, and macOS, but also new architectures such as ARM32 and ARM64. With PowerShell modules available for the major public and private clouds, you can leverage PowerShell to be more productive in cross‐cloud or hybrid scenarios. We still maintain PowerShell's “sacred vow”— that learning a new language is hard, but with time invested learning PowerShell, we will continue to enable PowerShell users to expand their impact and productivity, such as serverless functions as a service and Jupyter Notebooks. I'm excited about the next phase of PowerShell that we started with PowerShell 7, but for me, this is really just a beginning, with many more great things to come! This book from Thomas is a great way to get started on PowerShell 7, leveraging existing experience from Windows PowerShell.

Thomas Lee has been part of the PowerShell community far longer than I have been the engineering manager for PowerShell. Some of the things I've learned about PowerShell have come from reading his articles and blog posts. As the PowerShell team was making progress toward our substantial PowerShell 7 release, Thomas was there the whole way, promoting, teaching, and informing the community of all the great things to come with PowerShell 7. The most important aspect of what makes PowerShell successful has been the community, and Thomas has been a significant part of that.

Introduction

Hello, and thank you for buying this book. I sat in the audience at the Professional Developers Conference in Los Angeles in 2003, where Jeffrey Snover introduced Monad, which was later to become Windows PowerShell. I was excited about what I saw and heard; it was a seminal moment in my career.

Today we have a new version of PowerShell, PowerShell 7, to get excited about all over again. The PowerShell development team, combined with a fantastic community, has taken PowerShell to a new level. I continue to be excited, and I hope you are.

Before you dive into the body of this book, I hope you might take a few moments to read this short introduction where I explain my motivation for writing the book, its structure, and how you can use the PowerShell scripts in this book using Hyper‐V VMs.

This book contains 10 chapters. The first chapter looks at setting up PowerShell 7 in your environment. Chapter 2 examines the issue of Windows PowerShell compatibility and shows how PowerShell 7 addresses this challenge. The remaining eight chapters cover various Windows Server features and how you manage them with PowerShell 7. Here's a short overview of what is in this book:

Chapter 1

: Setting Up a PowerShell 7 Environment:

In this chapter, you look at how to install PowerShell 7 and VS Code. VS Code is your replacement for the older Windows PowerShell ISE. The screenshots in this book show PowerShell code running in VS Code. In production, you could consider not using VS Code, or any GUI tool for that matter, on your server and instead rely on the PowerShell 7 console and remote text editing.

Chapter 2

: PowerShell 7 Compatibility with Windows PowerShell:

Compatibility with Windows PowerShell is both an important objective and a significant engineering task. This chapter describes the compatibility issue as well as providing some additional background on modules. The chapter then looks at how backward compatibility works and discusses the small number of Windows PowerShell that you cannot use in PowerShell 7.

Chapter 3

: Managing Active Directory:

AD is at the heart of almost every organization's network. This chapter shows how you can deploy and manage AD, including creating forests and domains as well as linking forests with cross‐forest trusts. The chapter also looks at how you manage AD users, computers, groups, and more.

Chapter 4

: Managing Networking:

In this chapter, you look at managing your network with PowerShell 7. You examine NIC configuration, as well as installing and managing both DNS and DHCP.

Chapter 5

: Managing Storage:

Storage is a crucial aspect of any computer system. You need somewhere to store your files and other data. This chapter looks at managing disks and volumes/partitions as well as using a third‐party module to manage NTFS permissions. The chapter also examines Storage Replica to replicate storage, possibly for disaster recovery. Finally, the chapter looks at using File Server Resource Manager to manage file quotas and file screening.

Chapter 6

: Managing Shared Data:

Once you have disks configured as volumes and partitions and you have set up permissions appropriately, you need to share that data across the network. This chapter looks at how you set up and configure an SMB file server and how to create and secure SMB file shares. The chapter also looks at setting up an iSCSI target and then using that target to deploy a highly resilient clustered scale‐out file server.

Chapter 7

: Managing Printing:

Printing has been a core feature of Windows since the beginning of Windows itself. This chapter shows how to set up and manage a print server. The chapter shows how to add a printer, how to add print drivers, how to print a test page, and how to set up a printer pool.

Chapter 8

: Managing Hyper‐V:

Hyper‐V is Microsoft's core virtualization product. This chapter shows you how to set up and manage Hyper V and how to create and manage Hyper‐V VMs. The chapter also looks at VM and VM storage movement and replication, vital topics for today's VM‐focused world.

Chapter 9

: Using WMI with CIM Cmdlets:

Windows Management Instrumentation has been a feature within Windows since NT 4. WMI provides you with access to information about your system and allows you to manage aspects of the system. WMI is useful to provide you with access to Windows functionality you cannot get via PowerShell cmdlets. This chapter explores the WMI components and shows you how to discover more. The chapter also looks at managing WMI events and shows how you can set up a permanent event handler to manage critical security events.

Chapter 10

: Reporting:

Knowing the status of your IT infrastructure is vital to being able to manage your computing estate. This chapter demonstrates how you can use PowerShell 7 to learn more about your infrastructure. The chapter looks at reporting on AD users and computers, the filesystem via FSRM, printer usage, and Hyper‐V host and VM usage. This chapter also looks at using performance logging and alerting to capture detailed performance information and create rich performance reports and graphs that show the performance of your infrastructure.

I wrote this book to show you, the IT pro, that moving to PowerShell 7 is easy and worth your while. Just like when moving your home, things are a bit different in PowerShell 7. But once you get settled in, you are unlikely to look back. Along with VS Code, PowerShell 7 is just better. And I hope that each chapter of this book demonstrates that.

This book assumes you are an IT professional wanting to learn how to make the most of PowerShell 7. You might be an active administrator, a consultant, or a manager. You should have a background in both Windows Server features and broadly what they do, along with an understanding of Windows PowerShell itself.

The book looks at a variety of core Windows features including Active Directory, File Services Resource Manager, WMI, printing, and more. Each chapter describes a feature area and the components with which you interact. Then the chapter shows you how you can use PowerShell 7 to deploy, manage, and leverage that feature.

In this book (and indeed any book on PowerShell), it's not possible to cover every aspect of every feature set of Windows. As Jeffrey Snover says, “To ship is to choose,” and I hope I have chosen wisely. I have also provided pointers to where you can find more information. You are welcome to email me and give me feedback ( [email protected]).

This book contains a variety of scripts that you can use to manage some aspects of Windows using PowerShell 7. You can download these scripts either from the Wiley site or from my GitHub repository at github.com/doctordns/Wiley20. In the unlikely event you discover an issue with any of the scripts or find issues with the documentation, please file an issue report on the GitHub repository (github.com/doctordns/Wiley20/issues).

A key goal in developing this book is to demonstrate how easily you can use PowerShell 7 to manage a Windows Server infrastructure. There is a difference in how you install it, and you have to get used to VS Code as a replacement to the ISE. Along the way, I discovered a few issues around compatibility with Windows PowerShell, and I discuss these in Chapter 2. It is time to move forward to PowerShell 7.

I built the scripts and the book content based on a set of Windows Server 2019 Datacenter edition Hyper‐V VMs. To get the most value from this book and the scripts it contains, you should build the VMs yourself and use them to test the scripts. Of course, you can use physical hosts as an alternative to virtual machines, but VMs are simpler to use. For readers who may not have the necessary hardware at hand, I include screenshots showing the output of each step of each script. To assist in creating the VMs, I have created a set of scripts. You can find these on GitHub; see Chapter 1 for more information on these scripts and how to obtain them.

One impressive aspect of PowerShell, from the beginning, is the rich and vibrant PowerShell community. There are hundreds of people around the world who love PowerShell and have delivered all kinds of goodness: tweets, forum posts, blog articles, scripts, modules, web sites, and more. A fair number of features in PowerShell 7 come from the community.

Should you have any problem with any aspect of any component of this book—or any aspect of Windows—there is no shortage of help and guidance you can find on the Internet.

Pretty much any social media site where techies can congregate is going to have PowerShell content, help, and assistance. Feel free to visit the PowerShell forum on Spiceworks where I am a moderator (community.spiceworks.com/programming/powershell).

With that said, enjoy the book and enjoy PowerShell 7.

Fare thee well now,Let your life proceed by its own design.Nothing to tell now,Let the words be yours; I'm done with mine.“Cassidy,” John Barlow/Robert Weir
