Hi
Have you checked that you have not copies anything PHP or Apache relates into the windows or windows\stystem32 folders from the XAMPP or MAMP installs.
Primarily any php.ini files or httpd.conf file or my.ini files
Also check that you do not have anything on the windows path relating to XAMPP or MAMP installations. And of course nothing to do with the WAMPServer install.
The web is awash with bad/unnecessary advise to copy bit of this and that into windows folder and to put things on the windows PATH. This will always cause you issues when trying to use WAMPServers multi software feature and of course when you are trying to run all 3 installations on the same system
