The Windows PE (WinPE) boot images that are included with the Windows ADK have a minimal number of features and drivers. However the boot images can be customized by adding drivers, optional components, and applying the latest cumulative update.
Microsoft recommends updating Windows PE boot images with the latest cumulative update for maximum security and protection. The latest cumulative updates may also resolve known issues. For example, the Windows PE boot image can be updated with the latest cumulative update to address the BlackLotus UEFI bootkit vulnerability as documented in [KB5025885: How to manage the Windows Boot Manager revocations for Secure Boot changes associated with CVE-2023-24932](https://prod.support.services.microsoft.com/topic/kb5025885-how-to-manage-the-windows-boot-manager-revocations-for-secure-boot-changes-associated-with-cve-2023-24932-41a975df-beb2-40c1-99a3-b3ff139f832d) and [CVE-2023-24932](https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-24932).
This walkthrough describes how to customize a Windows PE boot image including updating with the latest cumulative update, adding drivers, and adding optional components. Additionally this walkthrough will go over how customizations in boot images affect several different popular products that utilize boot images, such as Microsoft Configuration Manager, Microsoft Deployment Toolkit (MDT), and Windows Deployment Services (WDS).

This walk-through isn't intended for use with Windows Server 2012 R2. Although the steps in this article may work with Windows Server 2012 R2 when using older versions of the Windows ADK, it may have compatibility problems with versions of the Windows ADK that are newer than the [ADK for Windows 10, version 2004](/windows-hardware/get-started/adk-install#other-adk-downloads). For server OSes, it's recommended to use Windows Server 2016 or later for this walk-through. For more information, see [Windows Server 2012 R2 Lifecycle](/lifecycle/products/windows-server-2012-r2).
