You can use CommandManager.RegisterClassCommandBinding to hook up a handler to every Window application wide. This will be continue working for the rest of your application run so it usually makes sense to put it in App.xaml.cs but you could put it anywhere.

CommandManager.RegisterClassCommandBinding(typeof(Window), new CommandBinding(ApplicationCommands.Cut, CutExecuted));
