How can I use `wmic` in a Windows PE script?

Question

I'm trying to determine the computer model (e.g., "Optiplex 9010") in a batch script running in the context of Windows PE 3.1. When running Windows proper, I can do this using wmic csproduct or wmic bios but neither of these return any data when running Windows PE. (This also seems to be true of most or all other classes.)

I've already installed the winpe-wmi.cab package to support WMI. Using wmic path instead of an alias makes no difference.

How can I make my wmic commands work?

Answer 1

It turns out that most wmic commands, including both wmic csproduct and wmic bios, will work if you install the winpe-scripting.cab package in addition to the winpe-wmi.cab package.
