Apache Server Running on a Windows Server Machine

To my understanding, when Apache is started on a windows machine, it will initiate 2 httpd processes, one parent and one child.

The child will then spawn multiple threads to handle incoming requests from clients.

My question is why do I then see more than 2 httpd processes in Task Manager?

Initially, it is 2 as I would expect but evenually, I start seeing 3, 4, 5, 6, ...

Thanks,
