Answer 1

If you want to trach system language changes then you have SystemEvents object which contains UserPreferenceChanged event you can attach to.

Sample:

Microsoft.Win32.SystemEvents.UserPreferenceChanged += new UserPreferenceChangedEventHandler(SystemEvents_UserPreferenceChanged);

If you want to track input language changes (like changes in system try when you choose between languages), then you can use: System.Windows.Forms.InputLanguage.CurrentInputLanguage

Sample:

string inputLanguage = System.Windows.Forms.InputLanguage.CurrentInputLanguage.LayoutName;

Answer 2

You can handle the SystemEvents.UserPreferenceChanged event:

void SystemEvents.UserPreferenceChanged(object sender, UserPreferenceChangedEventArgs e)
{
    // Regional settings have changed
    if (e.Category == UserPreferenceCategory.Locale)
    {
        ...
    }
}
