Where in the registry is the language setting for each user stored?Where in the registry is the language setting for each user stored?

A. The ID for the current language is stored in the registry value HKEY_CURRENT_USERControl PanelDesktopMultiUILanguageId. When you request a change to the language, the ID for the new language is stored in HKEY_CURRENT_USERControl PanelDesktopMUILanguagePending and takes effect at the next logon. Both registry values store a number that corresponds to the language ID you've chosen. The table below lists the available value.

If you request a language change, then want to cancel the change, you can open a registry editor and change the MUILanguagePending value to that of the MultiLanguageId value.
