I'm deploying WIndows 7 Enterprise x64 to a Latitude 5480 with 6th gen processor. During the MDT wizard, at the beginning of the deployment, the touchpad doesn't function. I have to use the keyboard to TAB around and make selections. After the OS is deployed the touchpad works fine. I have the latest WinPE 10 boot image drivers. Anyone else have this problem?
This could be due to the ADK kit you are using in the deployment server, Can you please try latest ADK1607 (boot image version:10.0.14393.0) in your deployment environment.
Please see below link for more information:
I believe you need to inject the Intel Serial IO Driver into your boot.wim
We had the same issue inside windows post deployment, where the trackpad didn't work, and installing the Intel Serial IO Driver fixed it.
