The file ToolkitDocumentation-x86_en-us.msi is a component of the Windows Assessment and Deployment Kit (ADK). It contains the local offline documentation for the various tools included in the kit, such as the Application Compatibility Toolkit (ACT) and the User State Migration Tool (USMT). Download Information
While Microsoft primarily distributes the ADK through a unified adksetup.exe (which downloads specific components on-demand), the individual .msi files are often cached during an offline installation process.
Official ADK Hub: For the most recent versions (Windows 11 and Windows 10), visit the official Windows ADK download page.
Offline Download Method: To obtain the specific .msi files (like the toolkit documentation) for offline use: Download adksetup.exe.
Run the installer from a command prompt with the /layout switch:adksetup.exe /layout "C:\ADKOffline".
The ToolkitDocumentation-x86_en-us.msi file will be located in the Installers subfolder of your specified path. Interesting Piece: The "Hidden" ADK Patching System
A notable recent shift in how the ADK is maintained is the introduction of ADK Patches as of December 2024.
Previously, updating the ADK required a full uninstallation and reinstallation—a tedious process for IT administrators managing large deployment shares. Now, Microsoft releases .msp (Windows Installer Patch) files, allowing users to update existing installations with bug fixes and security updates (like the recent fix for CVE-2026-25166 in the Windows System Image Manager) without rebuilding their entire environment from scratch.
