        System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
        //startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
        startInfo.FileName = "cmd.exe";
        startInfo.Arguments = $"/C {cmd}";
        process.StartInfo = startInfo;
        process.Start();
    }
   static void DisableInternet(bool enable)
    {
        string disableNet = "wmic path win32_networkadapter where PhysicalAdapter=True call disable";
        string enableNet = "wmic path win32_networkadapter where PhysicalAdapter=True call enable";
        runCmdCommad(enable ? enableNet :disableNet);
    }
