I've made some PowerShell (.ps1) and Batch (.bat) scripts that I would like to make part of an automated Windows installation. I have already configured everything else within my autounattend.xml file using the Windows System Image Manager and it works perfectly fine except for executing my scripts.

Before trying to go completely automated I used to enter Audit Mode (CTRL+SHIFT+F3) bypassing the OOBE and then run my scripts from there. Knowing my scripts worked in Audit Mode, within Windows System Image Manager I decided to insert synchronous commands at Pass 6 audituser.

This is my autouattend.xml file so far

I will be placing a directory called 'Scripts' at the root of the Windows install media so my question is, how do I call these scripts in the autounattend.xml from the install media? Is there a variable that links to the drive and path where the install media is?

I think I've found the solution.

  1. Extract the ISO/Windows installation media to a folder
  2. Create a folder inside sources\ directorie(s) of the extracted installation media called $OEM$
  3. Mirror the System drive so that you have a directory with the following path sources\$OEM$\$$\Setup\Scripts (C:\Windows\Setup\Scripts)

The $OEM$ folder mirrors the system drive so anything inside these folders gets copied across during setup. In regards to the scripts being run from the autounattend.xml file, you simply have to call the scripts from %SystemDrive%\WinDir\Setup\Scripts
