Start 10: latest version still not fully localized in Spanish
I understand if the installer is still in English, as it can be expected that most system admins have a working knowledge of English - that's just a reality of the IT world. However, the user options menu still being partially in English is pretty unacceptable, as you cannot expect users the world over to be able to read complex English options.
