# About

Core Components are the software tools and Windows features that must be in place on a Windows 11 build machine before running any OSDeploy workflow.

## Overview

OSDeploy runs on a Windows 11 workstation or server (amd64 or arm64) and uses these components at build time — not inside WinPE at deployment time. Some components are required for every workflow; others are needed only for specific tasks such as MDT integration, virtual machine testing, or script development. Use `Install-OSDeploySoftware` to install and manage all supported components from a single PowerShell command. Once the OSDeploy module is installed, run `Update-OSDeployCore` to download and cache all OSDeployCore assets — Windows Enterprise ESD files, OS images, and WinPE driver packages — before building boot images.

All components except PowerShell 7 and the PowerShell modules can be installed or downloaded using a single function: `Install-OSDeploySoftware`. Run it without parameters to list all available components and the command to install each one.
{% endhint %}
