How can I get the kind of the application?

Question

Hi!!! I have a list of all active applications in my system using GetWindow() from the API. I can get their handles, the tittle af the applications, etc, but I want to know the kind of application it is. I mean.. if this window is open, I'd get the tittle, that is " C# Corner Forums - Microsoft Internet Explorer". Do you know if I could get only the application, that is "Microsoft Internet Explorer"? I know in this case, it seems obvious 'cos I could take it from the tittle, but with other applications is much difficult. Thanks;)
