I’ve been involved in a couple of threads on Microsoft communities like http://answers.microsoft.com/en-us/surface/forum/surfpro3-surfnetwork/using-surface-pro-3-in-europe-no-support-for/91d6f4ec-f9d1-4bfe-a0f5-f2bbd6517053 which highlight and issue that Microsoft doesn’t seem to care about.

If you read the above referenced thread, you can draw your own conclusions, but as *I* read the available information, Microsoft owes folks a localized optional driver.
