Here are some sources to look into:

Looks like you'll be using the Runtime class.

Answer 2

None of your links CFL_Jeff says anything of how to get active application windows (which I assume is what you want?

Don't think this can be accomplished with java or a simple windows commandline.

Here might be a way to do it in C#: Get the list of opened windows C#

Or you might have to take a look here: http://msdn.microsoft.com/en-us/library/windows/desktop/ff468919%28v=vs.85%29.aspx

An emergency solution might be to use the "tasklist /v" command and get all processes that have a "windowtitle" that differ from "I/T"(might be locale dependent), but that will give you tray icons aswell I'm afraid.

Edit: To get the tasklist, you can use the following:

try
{
    Process p = Runtime.getRuntime().exec("cmd /c tasklist /v");
    BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
    String input;
    while ((input = stdInput.readLine()) != null)
    {
        output += input;
    }
    stdInput.close();
}
catch(Exception k){JOptionPane.showMessageDialog(null, k.getMessage());}
