Hi,
Wampserver, it is three services : wampapache64, wampmysqld64 and wampmariadb64 ( or wampapache, wampmydsqld and wampmariadb for the 32bit version).
These services can be started, stopped, deleted, recreated by Wampserver via the internal menus of Wampmanager (Aestan Tray Menu).
The installation of Wampserver does not interfere with another server unless the services use the same ports and are not stopped before.
