@Kran2022, Welcome to Microsoft Q&A, you could try to use Process.StandardOutput to check if the reagentc is disable.

    internal class Program
    {
        static void Main(string[] args)
        {
            var proc = new Process
            {
                StartInfo = new ProcessStartInfo
                {
                    FileName = "C:\\Windows\\System32\\ReAgentc.exe",
                    Arguments = "/info",
                    UseShellExecute = false,
                    RedirectStandardOutput = true,
                    CreateNoWindow = true
                }
            };
            proc.Start();
            while (!proc.StandardOutput.EndOfStream)
            {
                string line = proc.StandardOutput.ReadLine();
                // do something with line
                if(line.Contains("Windows RE status"))
                {
                    if(line.Contains("Disabled"))
                    {
                        Process newp = new Process
                        {
                            StartInfo = new ProcessStartInfo
                            {
                                FileName = "C:\\Windows\\System32\\ReAgentc.exe",
                                Arguments = "/enable",
                                UseShellExecute = false,
                                RedirectStandardOutput = true,
                                CreateNoWindow = false
                            }
                        };
                        newp.Start();


                    }
                }
               
            }
            Console.ReadKey();
        }
    }

@Jack J Jun Thanks so much. It looks console app with .3.1, 5.0 seems not supported.

I ran your code but it got stuck. Do i need to run as admin? thanks

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

@Kran2022 ,thanks for the response, based on my test, I could get some output in console app (net 5.0).

Please note that I have changed CreateNoWindow to be false in the following code:

 if (line.Contains("Windows RE status"))
                {
                    if (line.Contains("Disabled"))
                    {
                        Process newp = new Process
                        {
                            StartInfo = new ProcessStartInfo
                            {
                                FileName = "C:\\Windows\\System32\\ReAgentc.exe",
                                Arguments = "/enable",
                                UseShellExecute = false,
                                RedirectStandardOutput = true,
                                CreateNoWindow = false   //-> here I changed
                            }
                        };
                        newp.Start();


                    }
                }

Therefore, as usual, you are able to get some output in the console window.

BTW, after executing the app, you could use cmd to detect if the status of recovery has been changed again.

@Jack J Jun Hi there, thanks again. Something is not good, even your original code CreateNoWindow = false

I also chnaged it the project proprties and set .net 5.0, still i'm experiencing same issue. Any clue? thanks so much

To automatically close the console when debugging stops, enable Tools->Options->Debugging->Automatically close the console when debugging stops.

using System;
using System.Diagnostics;

    class Program
    {
        static void Main(string[] args)

                StartInfo = new ProcessStartInfo
                {
                    FileName = "C:\\Windows\\System32\\ReAgentc.exe",
                    Arguments = "/info",
                    UseShellExecute = false,
                    RedirectStandardOutput = true,
                    CreateNoWindow = true
                }
            };
            proc.Start();

                                CreateNoWindow = false
                            }
                        };
                        newp.Start();


                    }
                }

            }
            Console.ReadKey();
        }
    }
}

@Kran2022, if you execue the command Reagentc /enable in the Command Prompt, what will you see in the window?

I could get the same result between cmd window and console window:

Therefore, you could get the same result at least.

@Kran2022, thanks for the feedback, after checking your picture,

please noted that Windows RE status has been set to Enabled. Therefore, there is no need to Enable it again.

Also, I want to mention that my System is the English System and your Sytem is not the English System. Maybe you need to make some changes here.

if (line.Contains("Windows RE status")) { if (line.Contains("Disabled"))
