title: Find if process is running in Windows psutil
body: <pre><code>process_name = "CCC.exe"
  for proc in psutil.process_iter():
      if proc.name == process_name:
          print ("have")
      else: 
          print ("Dont have")
  </code></pre>
  
  <p>I know for the fact that CCC.exe is running. I tried this code with both 2.7 and 3.4 python
  I have imported psutil as well. However the process is there but it is printing "Dont have".</p>
