OSDeploy 26.5.27-previewnuget

Overview

The OSDeploy module is the build-time counterpart to OSDCloud. It runs on a full Windows 11 25H2 or later installation — not inside WinPE — and is responsible for creating and customizing WinPE boot images. The module automates the entire boot image pipeline: pulling in Windows ADK optional components and language packs, injecting WinPE drivers, embedding the OSDCloud PowerShell module, adding WinPE apps and console configuration, and generating bootable ISO files and USB drives.

Use Invoke-OSDeployHydration for a fully automated end-to-end build, or use Build-OSDeployBoot directly for fine-grained control over individual boot image builds.
