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.
