Thought I'd share my build script for automating the creation and maintenance of PE 4.0 builds. It works using only the official Microsoft Windows ADK for Windows 8. It can use the x86 or AMD64 versions of ADK, and will build x86 or AMD64 versions of Windows PE 4.0, with drivers, additional components and scripts.
It's a batch script that's easy to understand and edit, and it will create ISOs (with BIOS and EFI support), will automatically upload/freshen boot images on the WDS server(s), and will give you an onscreen prompt how to make a bootable USB key:
