Как отмена VIM является используемым деревом?

Запрос WMI:

"Select * from Win32_OperatingSystem"

РЕДАКТИРОВАНИЕ: На самом деле лучше был бы:

"Select Version from Win32_OperatingSystem"

Вы могли реализовать это в Дельфи как так:

function OperatingSystemDisplayName: string;

  function GetWMIObject(const objectName: string): IDispatch;
  var
    chEaten: Integer;
    BindCtx: IBindCtx;
    Moniker: IMoniker;
  begin
    OleCheck(CreateBindCtx(0, bindCtx));
    OleCheck(MkParseDisplayName(BindCtx, PChar(objectName), chEaten, Moniker));
    OleCheck(Moniker.BindToObject(BindCtx, nil, IDispatch, Result));
  end;

  function VarToString(const Value: OleVariant): string;
  begin
    if VarIsStr(Value) then begin
      Result := Trim(Value);
    end else begin
      Result := '';
    end;
  end;

  function FullVersionString(const Item: OleVariant): string;
  var
    Caption, ServicePack, Version, Architecture: string;
  begin
    Caption := VarToString(Item.Caption);
    ServicePack := VarToString(Item.CSDVersion);
    Version := VarToString(Item.Version);
    Architecture := ArchitectureDisplayName(SystemArchitecture);
    Result := Caption;
    if ServicePack <> '' then begin
      Result := Result + ' ' + ServicePack;
    end;
    Result := Result + ', version ' + Version + ', ' + Architecture;
  end;

var
  objWMIService: OleVariant;
  colItems: OleVariant;
  Item: OleVariant;
  oEnum: IEnumvariant;
  iValue: LongWord;

begin
  Try
    objWMIService := GetWMIObject('winmgmts:\\localhost\root\cimv2');
    colItems := objWMIService.ExecQuery('SELECT Caption, CSDVersion, Version FROM Win32_OperatingSystem', 'WQL', 0);
    oEnum := IUnknown(colItems._NewEnum) as IEnumVariant;
    if oEnum.Next(1, Item, iValue)=0 then begin
      Result := FullVersionString(Item);
      exit;
    end;
  Except
    // yes, I know this is nasty, but come what may I want to use the fallback code below should the WMI code fail
  End;

  (* Fallback, relies on the deprecated function GetVersionEx, reports erroneous values
     when manifest does not contain supportedOS matching the executing system *)
  Result := TOSVersion.ToString;
end;
