I’ve written a small app that modifies a setting for IE and need to somehow tell
IE to re-read the registry settings.
Does anyone know of an API call or message that will do this?

uses
  WinInet;

procedure IE_Reread_Registry_Settings;
var
  HInet: HINTERNET;
begin
  hInet := InternetOpen(PChar('YourAppName'), INTERNET_OPEN_TYPE_DIRECT,
    nil, nil, INTERNET_FLAG_OFFLINE);
  try
    if hInet <> nil then
      InternetSetOption(hInet, INTERNET_OPTION_SETTINGS_CHANGED, nil, 0);
  finally
    InternetCloseHandle(hInet);
  end;
end;
