Desmarcando a Opção “Detectar automaticamente as configurações” em Configurações da LAN em Opções da Internet com Delphi

• Crie um Formulário;
• Adicione um Botão;
• Adicione na cláusula USES:

  uses 
    Registry;
  

• No Botão adicione o código abaixo:

procedure TForm1.BitBtn1Click(Sender: TObject);
var
    Buffer : array [0..87] of Byte;
    Reg: TRegistry;
begin
  Reg := TRegistry.Create(KEY_WRITE);
