Hi @Peter_1985 , Welcome to Microsoft Q&A,

Append "/c" to the command line argument, which instructs Command Prompt to execute the command and then terminate.

Please ensure the following:

1. The application itself must have sufficient permissions to run the netsh command. This usually requires running the application as an administrator.
2. The netsh command in fld1 must be a valid and correctly formatted command. Please make sure that the commands in fld1 can be executed correctly in the command prompt.
3. If the user cancels the prompt for administrator privileges, the catch** block will catch the System.ComponentModel.Win32Exception exception, and you can add appropriate handling code there.

System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();

startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/c " + fld1; // Use "/c" to run the command and then terminate
startInfo.Verb = "runas";

process.StartInfo = startInfo;

try
{
     process.Start();
     process.WaitForExit();
}
catch (System.ComponentModel.Win32Exception ex)
{
     // Handle exceptions, e.g., if the user cancels the elevation prompt
     // MessageBox.Show(ex.Message);
}

Best Regards,

Jiale
