如何使用C#关闭Windows7网络时间同步？

using System;
using System.Diagnostics;

class Program
{
    static void Main()
    {
        try
        {
            Process process = new Process();
            process.StartInfo.FileName = "cmd.exe";
            process.StartInfo.Arguments = "/c net stop w32time";
            process.StartInfo.RedirectStandardOutput = true;
            process.StartInfo.UseShellExecute = false;
            process.Start();

            process.WaitForExit();
            process.Close();
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error: " + ex.Message);
        }
    }
}
