System Locale
When you choose a language on the Regional Settings (or Options) screen, a system locale is established as the basis for interacting with the system; Windows interactions of certain applications (such as Personal Communications) are governed by this setting.
Personal Communications uses the settings specified in Regional and Language Options → Advanced → Language for non-Unicode programs.
Note:
- Windows common dialogs, such as file open and print, may not change to match the system locale; they will be displayed in the language chosen when Windows was installed.
- The actions needed to switch system locales depend on the languages installed and the version of Windows. Refer to your Windows documentation for details.
