I have a problem where the user has set their locale (German) which is different that the Language Windows was installed as (English). Is there a way to discover what language windows was installed to use vs. what locale the user has set? I should note the issue is I am creating a Share and I set the permissions based on the Locale so if the User has set the Locale to German the permission for "Everyone" is "Jeder" but if the OS is setup for English this will fail since the is not an Id for "Jeder"
Thanks
Windows has the concept of the "UserLanguage" and the "SystemLanguage". What you are asking for is the SystemLanguage. Get that, and you'll have the correct answer.
Update: The Win32 function you want is GetSystemDefaultUILanguage()
Retrieves the language identifier for the system default UI language of the operating system, also known as the "install language" on Windows Vista and later.

Note that Windows Installer can query the property "SystemLanguageId". (in case you're interested from an instller point of view)
