Paul Thurrott has released the sixth major revision of his definitive Windows 11 manual, now dubbed the Windows 11 Field Guide 2026 edition. This June 2026 update renames and reorients the long-running ebook around the current supported version of Windows 11, delivering fresh chapters on year-based feature updates, deprecated and removed applications, and a deepened security segment.

Thurrott’s guide first appeared in beta form alongside the original Windows 11 launch in October 2021 and has since become a staple for IT professionals, enthusiasts, and anyone seeking a thorough, no-nonsense walkthrough of Microsoft’s flagship operating system. The decision to append “2026” to the title signals a strategic shift: rather than incremental patches, the book now mirrors Windows 11’s own annual update cadence.

For readers who have been following the series from its inception, the 2026 edition marks a maturation of both the author’s voice and the platform itself. Early editions spent pages detailing new taskbar layouts, Snap Layouts, and the Windows Subsystem for Android. Many of those features have since been deprecated or fundamentally changed. Thurrott has stripped away outdated advice and replaced it with what matters in mid-2026.

The evolution of a Windows 11 essential

When the original Windows 11 Field Guide landed, it was a rapid-response effort to explain a just-released OS that broke with a decade of Windows 10 conventions. Thurrott, a longtime Microsoft reporter and author of the famous WinSuperSite, self-published the book via Leanpub, enabling continuous updates. That model allowed him to push corrections and new content within hours of a Patch Tuesday or feature drop.

Version two arrived in 2022 with coverage of the 22H2 update, followed by yearly editions that tracked 23H2, 24H2, and now the latest production release. The 2026 edition drops the "version" numbering entirely, adopting a year-stamped brand that Microsoft itself has abandoned for consumer communications but that Thurrott clearly finds more intelligible for a reference book.

The ebook remains a Leanpub exclusive, available in PDF, EPUB, and MOBI formats, with free updates for existing purchasers. Thurrott’s commitment to regular revisions means a one-time purchase gives readers access to future versions, a model that has cultivated a loyal following.

What’s new in the 2026 edition

The title’s three pillars—year-based updates, removed apps, and new security chapters—tell much of the story. But underneath them lies a comprehensive rewrite that accounts for two years of Windows 11 evolution since the 2024 guide.

Year-based updates become the organizing principle

Microsoft’s shift to annual feature updates for Windows 11 (routinely labeled 23H2, 24H2, etc.) has created a documentation headache for third-party authors. Thurrott’s solution is to treat each annual release as a discrete chapter that sits alongside the core OS material. The 2026 edition includes dedicated breakdowns of 24H2 and 25H2, with forward-looking notes on what the 26H2 update might bring based on Insider builds.

This modular structure makes the book work as both a linear read and a reference. An IT admin who just inherited a fleet of 24H2 machines can jump straight to that chapter without wading through months of outdated text. At the same time, the overlapping nature of some features—Copilot integration, Start menu revisions, File Explorer changes—is acknowledged with cross-links and repeated key facts where necessary.

Thurrott doesn’t shy away from editorializing. He calls out features that have been summarily yanked (the much-hyped “Windows Copilot” sidebar that was replaced by the Microsoft 365 Copilot app), questions the logic of certain UI changes, and offers workarounds for those who prefer the old ways.

Deprecated and removed applications get their own chapter

One of the most requested additions from readers is a clear inventory of what Microsoft has killed. The 2026 edition delivers with a chapter titled “Removed & Deprecated: What’s Gone from Windows 11.” It covers:

  • WordPad, removed in Windows 11 24H2 and no longer available even as a Feature on Demand.
  • Cortana, the beleaguered assistant that was discontinued as a standalone app in late 2023.
  • Windows Mixed Reality, axed in a move that surprised many enterprise users.
  • Tips and Feedback Hub streamlining.
  • Microsoft Support Diagnostic Tool (MSDT), retired in favor of the newer Get Help platform.
  • VBScript, deprecated and actively discouraged.

For each removed component, Thurrott explains the official replacement or workaround. When an official replacement doesn’t exist—as with WordPad—he suggests third-party alternatives like Notepad++ or the free Office web apps. The chapter also lists apps that are still present but flagged for future removal, such as the legacy Windows Media Player (in favor of the modern Media Player app) and the Steps Recorder (psr.exe).

This section alone makes the 2026 guide valuable for IT administrators who need to plan application migrations and for support staff fielding questions from confused end users who can’t find familiar tools.

An expanded security section

Security has been a centerpiece of every Windows 11 Field Guide, but the 2026 edition treats it as a standalone pillar. Three new chapters cover:

  • Windows Hello Enhanced Sign-in Security: How the new biometric safeguards work, which hardware qualifies, and the implications for passwordless strategies.
  • Microsoft Pluton: The security chip now embedded in many 2024–2026 laptops, how it differs from TPM 2.0, and what it means for BitLocker, Credential Guard, and Secure Boot.
  • Passkeys and the future of authentication: A practical walkthrough of setting up passkeys in Windows 11, syncing them via Microsoft or third-party providers, and what happens when a device is lost.

Thurrott contextualizes these features within real-world scenarios, such as the rise of token theft attacks and the growing regulatory pressure for phishing-resistant MFA. The chapters don’t read like dry whitepapers; they’re written in the same conversational tone as the rest of the book, with plenty of screenshots and step-by-step instructions.

Beyond the headline additions, the 2026 edition reflects two years of smaller yet important changes: the redesigned Quick Settings panel, the death of Windows Subsystem for Android, the deeper integration of Copilot across the shell, improvements to the Task Manager, and the new Outlook for Windows that replaced the classic Mail and Calendar apps.

Why the guide still wins over official documentation

Microsoft publishes its own documentation on Learn (learn.microsoft.com), and it’s extensive. But as any IT pro can attest, that documentation is often reference-oriented, fragmented, and slow to reflect the reality of a freshly shipped feature update. Thurrott’s guide fills the gap between technical reference and user manual.

He writes for the person who just bought a new laptop and wants to understand everything Windows 11 can do, as well as for the veteran administrator who needs to know the precise registry key to suppress a unwanted taskbar icon. His prose is direct, occasionally sardonic, and free of the marketing spin that infects many corporate guides.

The 2026 edition also benefits from Thurrott’s ongoing reporting at Thurrott.com. He routinely breaks news about upcoming Windows changes, tests Insider builds, and maintains a pulse on the community’s frustrations. Those insights infuse the book with a level of candor rarely seen in official documentation.

Who should buy the Windows 11 Field Guide 2026

The guide is not for everyone. Casual users who only need to browse the web, check email, and use Office will find the built-in Windows Tips and online support sufficient. But for the following audiences, the $20 investment (the typical price over the years) delivers outsized value:

  • IT administrators and support technicians who manage Windows 11 deployments and need a single source of truth for configuration, troubleshooting, and training.
  • Power users who want to strip out bloatware, customize hidden settings, or understand exactly how Windows telemetry works.
  • Students and new PC owners who want to move from being intimidated by Windows to mastering it.
  • Windows Insiders and Microsoft enthusiasts who enjoy deep dives into the OS architecture and future roadmap.

Because the book is updated frequently, a one-time purchase gives access to all future editions. Thurrott has historically released major updates twice a year, aligning with Microsoft’s cumulative updates and feature drops, making it a living document.

A guide that grows with Windows 11

The renaming to Windows 11 Field Guide 2026 is more than marketing. It reflects a reality that Microsoft rarely acknowledges in its consumer messaging: Windows is now a yearly-moving target, and staying current requires deliberate effort. Thurrott’s guide is the most human-readable answer to that challenge.

As Windows 11 marches toward its fifth birthday, the platform has stabilized around a set of core features while continuing to shed legacy components and add new security capabilities. The 2026 edition captures that moment with precision. It doesn’t promise to make Windows 11 perfect, but it does promise to make it understandable—and, for the first time, to clearly show what’s been left behind.

For anyone tasked with living in Microsoft’s OS for the next year or more, the Windows 11 Field Guide 2026 is the companion that the built-in Get Help app wishes it could be.
