Hi Peter Ecki,
Based on Microsoft’s latest documentation, the special HID Mini driver for WinPE is still required for Surface Pro 10 and Surface Pro 11 (Intel) models to enable the Type Cover during Windows PE deployments. For the Surface Pro 12, however, the driver requirement has changed.
The Surface Pro 12 driver and firmware package already includes updated keyboard and HID components, so you don’t need to import the separate HID Mini driver when customizing your WinPE boot image. Instead, you should download the latest Surface Pro 12 MSI driver package from the official Surface driver and firmware site, extract it, and import the relevant folders into your WinPE image. This ensures the Type Cover and keyboard function correctly during ConfigMgr or MDT provisioning.
I hope the response provided some helpful insight. If you find this answer useful, please hit “accept answer” so I know it addressed your concern.
