Symptomer

Løsning

USB-C and Thunderbolt Docking Stations

An issue where several computers are unable to recognize USB-C or Thunderbolt docks. If you check Device Manager, you see a yellow exclamation mark (bang), and get a message if you try to automatically search for drivers on the device with Device Manager.
Update Driver Device Manager

Group Policy Setting

This is caused by a Group Policy (GPO) setting in the Windows image. The security policy is preventing USB-C and Thunderbolt devices and drivers from being installed. This was likely in the custom Windows image due to a previous vulnerability in Thunderbolt 1 & 2 that is no longer present in Thunderbolt 3 devices.

Dell is not able to provide specific Windows imaging assistance but if the Windows administrator is familiar with the GPOs. Review the following information in the link from Microsoft, and they can adjust their custom Windows image accordingly.
