title: How to avoid the Windows (XP) Security Warning when launching a "DOS" command line within C#?
body: <p>This question is related to <a href="https://stackoverflow.com/questions/2967795/windows-command-line-compression-extraction-tool">this initial question</a> asked a little while ago.</p>
  
  <p>Now, that I have chosen the extracting tool, I'm iterating through a given in command line parameter directory and subdirectories to extract the compressed .zip files.</p>
  
  <pre><code>private static void ExtractAll(DirectoryInfo _workingFolder) {
      if(_workingFolder == null) {
          Console.WriteLine("Répertoire inexistant.");
          return;
      }
  
      foreach (DirectoryInfo subFolder in _workingFolder.GetDirectories("*", SearchOption.AllDirectories)) 
          foreach(FileInfo zippedFile in subFolder.GetFiles("*.zip", SearchOption.AllDirectories)) {
              if(zippedFile.Exists) {
                  ProcessStartInfo task = new ProcessStartInfo(@".\Tools\7za.exe", string.Format("x {0}", zippedFile.FullName));
                  Process.Start(task);
              }
      }
  }
  </code></pre>
  
  <p>But everytime I start a 7za process, the Windows Security Warning prompts. I would like to avoid such annoying behaviour, so here's my question:</p>
