Hi,
It is not up to Wampserver to tell you how to install a "thing" on a server, it is up to the "thing" to explain how to install it on a Web server.
For example, what would you have read if you had bothered to go to the related documentation:
https://github.com/memcached/memcached/wiki/InstallMemcached works on most Linux and BSD like systems. There is no official support for windows builds.
You should think that one cannot know the installation procedures of thousands of WEB applications, hundreds of CMS and tens of thousands of "tricks" and "machines" that can be added to a web server.
