Configure a Windows Client to use an MCC Server Earlier than Early

When deploying Windows Clients in a location with a Microsoft Connected Cache (MCC) Server available, it is sometimes quite useful to inject those settings before Windows boots for the first time. For example, to allow the Enrollment State Page (ESP) in Windows Autopilot to download its applications from a local source.

Here is a PowerShell Script that you can use to inject the IP Address of the MCC Server during deployment, during the WinPE phase, or directly in the offline image. In this example, you must add code to find the right OS Volume drive letter and set the $OSDriveLetter variable accordingly. You find the script in our GitHub repository.
