title: Stub received bad data?
body: <p>Firstly, there is no problem executing the code on Win7/Win8 etc. The problem exists solely on Windows XP. The code is in a button, and basically runs taskmgr.exe as another users credentials (a local admin credentials, this is a Kiosk PC which loads a C# application which can be logged into and then load cmd.exe/taskmgr.exe as a local admin unaffected by the GPOs linked to the Kiosk user). </p>
  
  <p>However, on XP, I get the error when clicking the button: Stub received bad data.</p>
  
  <p>Code:</p>
  
  <pre><code>private void btnTaskMgr_Click(object sender, EventArgs e)
  {
      string password = "myPassword";
      SecureString secureString = new SecureString();
  
      foreach (char chr in password) secureString.AppendChar(chr);
  
      ProcessStartInfo processAdmin;
      processAdmin = new ProcessStartInfo();
      processAdmin.UseShellExecute = false;
      processAdmin.Password = secureString;
      processAdmin.UserName = "admin";
      processAdmin.FileName = "taskmgr.exe";
      processAdmin.WorkingDirectory = "C:\\Windows\\System32";
      Process.Start(processAdmin);
  
  }
  </code></pre>
