Mastering the Microsoft Deployment Toolkit

The MDT method of driver detection and injection

When we boot a target machine via our LiteTouch media, one of the initial task sequence steps will enumerate (via PnPEnum.exe) all of the PnP IDs for every device in the machine. Then, as part of the Inject Drivers task sequence step, we will search all of our Out-of-Box Driver INF files to find the matching driver, then MDT will utilize DISM to inject these drivers offline into the applied WIM.

Note

Note that, by default, we will be searching our entire Out-of-Box drivers repository and letting PnP figure things out.

We will later discuss how to force MDT to only choose from the drivers that we specify, thereby gaining strict control over which drivers actually get installed.
