          radioButton2.Checked = Key?.GetValue("ProxyEnable")?.ToString() == "0" ? true : false;

        private void radioButton1_CheckedChanged(object sender, EventArgs e)
        {
            RegistryKey saveKey = Registry.CurrentUser.CreateSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings");
            saveKey.SetValue("ProxyEnable", 1, RegistryValueKind.DWord);
            saveKey.Close();
        }

        private void radioButton2_CheckedChanged(object sender, EventArgs e)

            saveKey.SetValue("ProxyEnable", 0, RegistryValueKind.DWord);
            saveKey.Close();
