A simple method is to create a folder in “c:\windows\inf” . I use “c:\windows\inf\xinf”.
Because Windows 7 recursively searches folders for drivers, and since Windows 7 searches “c:\windows\inf” by default, there is no configuration required other than to drop each extracted driver into its own folder inside “c:\windows\inf\xinf”.
Be aware, that some drivers are coded for both x86 and x64. Some will load x64 when x86 is required or vice versa, causing a failure of varying degree.
Some drivers for some versions of hardware will load the wrong version and brick the system. I’m looking at you Intel USB 3.0 eXtensible Host Controller (series 7 vs series 8).
I’ve dropped x86 and x64 drivers that play nice together into my xinf folder. I then use a vb script called from sysprep that detects specific needs for specific make/models that we have in service, that then performs installations and configurations, all the while using auto-logon.
Importantly, I disable and set to manual, the FOG Service before I close an image with sysprep. Reactivating the FOG service is the last thing my script does because the FOG Service will ungracefully interrupt any running scripts and force a restart when an image is deployed with naming and domain-joining enabled.
