Execute batch file using windows service

I tried almost first 2 pages of google search with text "calling batch file from windows service". Still no luck. Also tried to edit registry of service (my service) as suggested in one of the link. My service is running under "Network services" account

Here is my sample code

private static void InvokeBatchFile()
        {
            using (System.Diagnostics.Process process = new System.Diagnostics.Process())
            {
                process.StartInfo.WorkingDirectory = Environment.GetFolderPath(Environment.SpecialFolder.System);
                process.StartInfo = new System.Diagnostics.ProcessStartInfo(@"c:\windows\system32\cmd.exe");
                process.StartInfo.FileName = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System), "cmd.exe");

               process.StartInfo.Arguments = string.Format(@"/C C:\data\test.bat");
                process.StartInfo.CreateNoWindow = true;
                process.StartInfo.ErrorDialog = false;
                process.StartInfo.UseShellExecute = false;
                process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
                process.StartInfo.RedirectStandardOutput = true;
                process.StartInfo.RedirectStandardError = true;
                process.StartInfo.RedirectStandardInput = true;

                process.Start();

             

            }
        }
