Answer 1

Using Process.GetProcesses(); method you can get all running application and if you want current active window then make use of GetForegroundWindow() and GetWindowText() .

Answer 2

You can use the Process class. It has a Modules property that lists all the loaded modules.

To list all processes and all modules to the console:

Process[] processes = Process.GetProcesses();

    foreach(Process process in processes) {
    Console.WriteLine("PID:  " + process.Id);
    Console.WriteLine("Name: " + process.Name);
    Console.WriteLine("Modules:");
    foreach(ProcessModule module in process.Modules) {
        Console.WriteLine(module.FileName);
    }

Or do like this,

[DllImport("user32.dll")]
private static extern IntPtr GetForegroundWindow();

[DllImport("user32.dll")]
private static extern int GetWindowText(IntPtr hWnd, StringBuilder text, int count);

public static void Main()
{
    int chars = 256;
    StringBuilder buff = new StringBuilder(chars);
    while (true)
    {
        // Obtain the handle of the active window.
        IntPtr handle = GetForegroundWindow();

        // Update the controls.
        if (GetWindowModuleFileName(handle, buff, chars) > 0)
        {
            Console.WriteLine(buff.ToString());
            Console.WriteLine(handle.ToString());
        }
        Thread.Sleep(1000);
    }
}

From: How to get a process window class name from c#?

    int pidToSearch = 316;
    //Init a condition indicating that you want to search by process id.
    var condition = new PropertyCondition(AutomationElementIdentifiers.ProcessIdProperty, 
        pidToSearch);
    //Find the automation element matching the criteria
    AutomationElement element = AutomationElement.RootElement.FindFirst(
        TreeScope.Children, condition);

    //get the classname
    var className = element.Current.ClassName;

I am not sure how you are calling these programs. If you running these programs through Process, you can get through ProcessName.

Example:

        Process tp = Process.Start(@"notepad.exe", "temp");

        string s = tp.ProcessName;
