What will happen under Windows if the version of Windows is German but locale set to English, or other way around? There are other combinations to think about (Russian/German, Russian/English, etc.).
I don't understand your question. Do you mean setting the system UI language /"InstallLanguage" in Control Panel to another one? This isn't possible in a retail version of Windows. There are only changes possible for System/User/Thread(?) Locale, Input Locale, Geographic ID.
Do you think it would be possible to make a Wine test case that would show this behaviour (in usp10)?
