Change Process priority does not work

Question

I run an Audio Repeater application which allows me to play sound through my headset & Speakers at the same time. The Application itself has an ability to set itself to \"Re

You can run as an administrator or remove UAC because you need rights to access to a Process you did not run.

This works for me :

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

// #define DEBUG

namespace ProcessRealtime
{
    class PUBG_RealTime
    {
        static string processName = "TslGame";
        static ProcessPriorityClass newPriority = ProcessPriorityClass.High;

        static void Main(string[] args)
        {
#if DEBUG
            PutDebug("Start!");
#endif
            Process[] processes = Process.GetProcessesByName(processName);
#if DEBUG
            PutDebug(processes.Length + " processed found");
#endif
            foreach (Process proc in processes)
            {
#if DEBUG
                PutDebug("New process found");
#endif
                Console.WriteLine("Changing Priority for id:" + proc.Id + " to " + newPriority.ToString());
                proc.PriorityClass = newPriority;
#if DEBUG
                PutDebug("Changed priority for " + proc.Id);
#endif
            }
#if DEBUG
            PutDebug("No more processes..");
#endif
            Console.Write("Press a key, it's over !");
            Console.ReadLine();
        }

#if DEBUG
        static bool debug = true;
        static int debugInc = 1;
        static void PutDebug(string info = "")
        {
            if(debug){
                Console.WriteLine("Debug" + debugInc + ": " + info);
                debugInc++;
            }
        }
#endif
    }
}
