WM_SETTINGSCHANGE for locale settings and WM_TIMECHANGE for time changes.

You will get WM_INPUTLANGCHANGEREQUEST before the language is changed (and you can choose whether to accept or reject the change), and then WM_INPUTLANGCHANGE after the language is successfully changed (if you pass WM_INPUTLANGCHANGEREQUEST to the DefWindowProc).

WM_TIMECHANGE is sent whenever system time is changed.

WM_SETTINGCHANGE is also sent upon change of some modifications. However, it's done on a volunteer base by the app that changes the setting. One can assume standard Control Panel applets are fair players.
