Per Apache's documentation (https://httpd.apache.org/docs/2.4/platform/windows.html#page-header):
Because Apache for Windows is multithreaded, it does not use a separate process for each request, as Apache can on Unix. Instead there are usually only two Apache processes running: a parent process, and a child which handles the requests. Within the child process each request is handled by a separate thread.
