mpm_winnt_module is missing (1 reply)

I keep getting "The connection was reset" on localhost. Search on the Internet provided advice that I need to add the following section to config file:

<IfModule mpm_winnt_module>
ThreadStackSize 8388608
</IfModule>

However, the mpm_winnt_module did not come with the installation of WAMP 3.0.6. How can I add this module which seems to me "must have" on windows?
