using System;
using System.Collections.Generic;
using System.ComponentModel;

using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Management;
using System.Diagnostics;
using System.Threading;
using System.IO;

namespace mag_3
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            ManagementEventWatcher stopWatch = new ManagementEventWatcher(new WqlEventQuery("SELECT * FROM Win32_ProcessStopTrace"));

            try
            {
                stopWatch.EventArrived += new EventArrivedEventHandler(this.Bulk_);
                stopWatch.Start();
            }
            catch (Exception)
            {
                MessageBox.Show("Can't start the Process-Monitor! Are you running as admin?");
                return;
            }
        }

        private void Bulk_(object sender, EventArrivedEventArgs e)
        {
            Invoke(new MethodInvoker(() =>
            {
                listBox1.Items.Add(string.Format("Process stop: {0}", e.NewEvent.Properties["Second.exe"].Value));
            }));
        }

    }
}

@MiPakTeh , It is necessary for the app to have the Admin Power if we want to use WMI to monitor if the process is stopped.

Therefore, we have to force the app to run as Administrator all the time.

Please refer to the following steps to do it.

First, Please add a Application Manifest File in your app.

Second, Please modify the code in the manifest file like the following:

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />  

Third, Please restart your vs 2019.

Finally, the app can be used it in everybody with the Administrator Power.
