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:
  1. 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.
  2. The actions needed to switch system locales depend on the languages installed and the version of Windows. Refer to your Windows documentation for details.
