ManagementEventWatcher.Start()访问被拒绝

Question

我正试图在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() 上收到了"拒绝访问"

以下是到目前为止我得到的

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);
        }
    }
}

我在网上搜索了几个小时，但什么都找不到。有这个问题的人是在偏远地区，而不是在当地。我使用的是Windows Pro 8.1+Microsoft Visual Studio Ultimate 2013，以防VS或OS版本在这种情况下可能很重要。

问题在processStartEvent.Start()上触发，显示"访问被拒绝"。我还尝试从.Start()切换到.WaitForNextEvent()，得到了相同的结果

我这里有什么遗漏吗？
