Lock files are generally not used on Windows (and rarely on Unix).

You can not rely on lock files in Linux or Windows. I would just bite the bullet and iterate through all the running programs.

<code>win32ui.FindWindow(classname, None)</code> returns a window handle if any window with the given class name is found. It raises <code>window32ui.error</code> otherwise.

I found that the window class name for the Dropbox tray icon was DropboxTrayIcon using Autohotkey Window Spy.

I'd like to add this solution to the list, for historical purposes. It allows you to find out based on .exe instead of window title, and also returns memory used &amp; PID.

Similar with previously comment, you can use this function:

 context.controller.top_window().set_focus()

<code>backend</code> can be 'uia' or 'win32'

<code>timeout</code> if for force reconnect with the applicaction during 5 seconds.

I am trying to create a python script which I will later run as a service. Now I want to run a particular part of the code only when iTunes is running. I understand from some research that polling the entire command list and then searching for the application for that list is expensive. 

I found out that processes on UNIX-based operating systems create a lock file to notify that a program is currently running, at which point we can use <code>os.stat(location_of_file)</code> to check if the file exists to determine if a program is running or not.

Is there a similar lock file created on Windows?

If not what are the various ways in Python by which we can determine if a process is running or not?
