Windows10で2つのApacheが起動している

Windows10にApacheをインストールして、プロセスを確認してみるとApacheが2つあった。

おかしいなと思って調べてみるとWindowsではこれで大丈夫なようです。

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.
