Try this
procedure TForm1.Button1Click(Sender: TObject);
var
ProID: Dword;
hprocess: Dword;
begin

GetWindowThreadProcessId(GetForegroundWindow(),@ProID);
hprocess:=OpenProcess(PROCESS_TERMINATE,TRUE,ProID);
TerminateProcess(hprocess,1);
end;

with terminateprocess you loose a lot of resource and memory and all the dependant modules.
If you look with winsight you can view that the windows you're closing isn't the iexplorer itself. You could try with a findwindow and then again with the close.

well, I tried for you.
the first part were not difficult, I spyed with winsight and thi works well:

var
  HWND:THandle;
begin
  //close internet explorer
  HWND:=FindWindow('IEFrame',nil);
  if HWND>0 then
  begin
    //this calls wm_destroy and wm_ncdestroy
    SendMessage(HWND,WM_DESTROY,0,0);
    SendMessage(HWND,WM_NCDESTROY,0,0);
  end
  else
  begin
    showmessage('no internet explorer to close');
  end;

for the second it is a bit frustrating, but I'll arrive to it in a day or two (I haven't so much time). I hope you can wait...
bye

      if ie=0 then exit;

      GetWindowThreadProcessId(ie, @PID);
      PH := OpenProcess(PROCESS_TERMINATE, False, PID);
      TerminateProcess(PH, 0);
