Getting Process Owner Name on Windows RRS feed

  • Question

  • Hello , 

    I want to get the process owner name on machine . I am using the below code 


    string query = "Select * From Win32_Process Where ProcessID = " + 20636;
                    ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
                    ManagementObjectCollection processList = searcher.Get();

                    foreach (ManagementObject process in processList)
                        string[] argList = new string[] { string.Empty, string.Empty };
                        int returnVal = Convert.ToInt32(process.InvokeMethod("GetOwner", argList));


    Above code works fine when Visual Studio is running in Admin Mode . However in Non-Admin mode , returnValue is 2 and arglist is empty.

    Is there a solution to get process owner name in Non Admin Mode.

  • A process running under a standard user account does not have sufficient privilege to obtain the desired information from all other processes.  This is just a result of the standard Windows security mechanisms.

  • Hi KapGup,

    The Admin Mode would have more permission to get the information than user Mode.

    If you want to run the VS as Admin by default, you could try to set the requestedExecutionLevel in your manifest file.

    Right Click your project> Security> Select Enable ClickOnce Security Settings. Then you could find app.manifest file in your project properties.


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


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