The instance is an index-like property for win32 windows which share the same class name, sorted by [x,y]. In some cases this is the only way to distinguish two windows (not including the volatile handle).

For example if there are two windows with class 'MyWndClass123' (and the same parent window) then one window has instance '0' and the other has instance '1'.
