We are using Zenworktodo to apply a Windows 7 Third Party Image in WIM format and using the Powershell script mentioned here: Windows 7 Automated Imaging and ZCM Registration | Novell User Communities

I wounder how Add-on Images works. Can I apply an addon image in my preboot bundle after the Windows 7 image? It seems like Zenworktodo is applying the Windows 7 image and then restarts the computer and finishes the installation without moving on to the next step in the preboot bundle..

What is the best way of applying addon images when using WIM files?
Can you use an Windows 7 WIM image and then apply zmg images?
