WinPE 4.0 - Automated Media Creation

I maintain two Windows 8 VMs for building WinPE 4.0, one for x86 and one for x64. Unlike the Windows 7 WAIK, Apparently the Windows 8 ADK can only build x86 on x86, and x64 on x64.

This Powershell 3 script is intended to be run from a network share with subdirectories containing apps (optional) and drivers (optional), and looks something like this:

.\setup_w8_ps3.ps1

.\drivers\amd64

.\drivers\source

.\drivers\x86

.\apps\amd64

.\apps\source

.\apps\x86

Source directories contain the source files and the x86 and amd64 directories contain the expanded x86 and x64 drivers, respectively.

Run the Powershell script on each of your x86 and x64 Windows 8 ADK environments, and it will build the respective WinPE 4.0 environment and .iso file.

There is one extra step for making the USB boot sticks [ MakeWinPEMedia /UFD c:\winpe_amd64 <drive letter>: ]; You can add that to the Media function if you have the USB drive plugged in.
