At least we have an element title: [One] class: [Button]

Having the following values for all properties:
Title is: <One>	Class   := <Button>	controltype:= <UIA_ButtonControlTypeId>	,<50000>	, (0000C350)	1480;908;171;117
*** Parent Information top down ***
2: Title is: <Calculator>	Class   := <ApplicationFrameWindow>	controltype:= <UIA_WindowControlTypeId>	,<50032>	, (0000C370)	1293;218;1215;939
"Title:=Calculator;controltype:=UIA_WindowControlTypeId;class:=ApplicationFrameWindow""
1: Title is: <Calculator>	Class   := <Windows.UI.Core.CoreWindow>	controltype:= <UIA_WindowControlTypeId>	,<50032>	, (0000C370)	1300;218;1200;932
"Title:=Calculator;controltype:=UIA_WindowControlTypeId;class:=Windows.UI.Core.CoreWindow""
0: Title is: <>	Class   := <LandmarkTarget>	controltype:= <UIA_GroupControlTypeId>	,<50026>	, (0000C36A)	1480;667;521;477
