I noticed I'm wrong about the update location for the amdxata.
You would need to be at the site of Dell to update the drivers.

Dell is not testing or developing Windows 10 drivers for Dell Studio XPS 7100. If you choose to upgrade, some features, applications, and connected devices may not work as expected.
