This is not exposed by the VCL framework. Instead you need to dip into the Win32 API. The function you need is GetWindowPlacement.

var
  WindowPlacement: TWindowPlacement;
....
WindowPlacement.length := SizeOf(WindowPlacement);
Win32Check(GetWindowPlacement(Form.Handle, WindowPlacement));

The information you need can be found in the WindowPlacement struct. Do beware that the coordinates are reported with respect to the work area rather than the screen.

Generally you want this information so that you can restore it at a later date. Use SetWindowPlacement to do that.
