ManagementEventWatcher.Start() 拒绝访问

Question

我正在尝试在 C#.Net 中创建一个应用程序，我需要它来扫描用户启动和停止的进程，但我在 .Start()

这是我目前得到的

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Security.Cryptography;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;

using MySql.Data.MySqlClient;
using System.Management;
using Security;
using MySQLConnectivity;

namespace MyApp
{
    public partial class Login : Form
    {
        MySQLClass sql = new MySQLClass();
        ManagementEventWatcher processStartEvent = new ManagementEventWatcher("SELECT * FROM Win32_ProcessStartTrace");
        ManagementEventWatcher processStopEvent = new ManagementEventWatcher("SELECT * FROM Win32_ProcessStopTrace");

        public Login()
        {
            InitializeComponent();
            processStartEvent.EventArrived += new EventArrivedEventHandler(processStartEvent_EventArrived);
            processStartEvent.Start();
            processStopEvent.EventArrived += new EventArrivedEventHandler(processStopEvent_EventArrived);
            processStopEvent.Start();
        }

        void processStartEvent_EventArrived(object sender, EventArrivedEventArgs e)
        {
            string processName = e.NewEvent.Properties["ProcessName"].Value.ToString();
            string processID = Convert.ToInt32(e.NewEvent.Properties["ProcessID"].Value).ToString();

            MessageBox.Show("Process started. Name: " + processName + " | ID: " + processID);
        }

        void processStopEvent_EventArrived(object sender, EventArrivedEventArgs e)
        {
            string processName = e.NewEvent.Properties["ProcessName"].Value.ToString();
            string processID = Convert.ToInt32(e.NewEvent.Properties["ProcessID"].Value).ToString();

            MessageBox.Show("Process stopped. Name: " + processName + " | ID: " + processID);
        }
    }
}

我搜索了在线时间，但找不到任何内容。遇到这个问题的人是远程遇到的，而不是本地遇到的。我正在使用 Windows Pro 8.1 + Microsoft Visual Studio Ultimate 2013，以防万一 VS 或 OS 的版本在这种情况下可能很重要。

问题在 processStartEvent.Start() 说 "Access denied" 时触发。我也尝试从 .Start() 切换到 .WaitForNextEvent()，结果相同

我在这里遗漏了什么吗？
