// GetDesktopListView
// Desktop Listview Handle ermitteln
// Author: Nico Bendlin

function GetDesktopListView: HWND;
var
  Progman: HWND;
  DefView: HWND;
  function EnumDefViewProc(Wnd: HWND; out DefView: HWND): BOOL; stdcall;
  var
    ClassName: array[0..255] of Char;
  begin
    DefView := Wnd;
    ClassName[0] := #0;
    GetClassName(Wnd, ClassName, 255);
    Result := lstrcmp(ClassName, 'SHELLDLL_DefView') <> 0;
  end;
begin
  Result := HWND(nil);
  Progman := FindWindow('Progman', nil);
  if Progman <> HWND(nil) then

  end;

type
  TFNIsWow64Process = function(hProcess: THandle; out Wow64Process: BOOL):

var
  FNIsWow64Process: TFNIsWow64Process;
Die is aber recht kompliziert ...

Es gibt möglich Dinge und unmöglich Dinge.
Für unmögliche braucht man lediglich etwas länger.
