WampServer is a Windows-based Web development platform, without Internet access, for dynamic Web applications using the Apache 2.4 server, PHP scripting language and a MySQL and/or MariaDB database. Includes PHPMyAdmin and Adminer for database management. WampServer automatically installs everything you need to intuitively develop Web applications. You can adjust your server without touching its configuration files, using the various left-click and right-click menus of the Tray Menu Manager installed in the taskbar.

Important Reminder: The transfer of databases between different versions of MySQL or MariaDB should be performed by EXPORT / IMPORT of SQL files using phpMyAdmin or a similiar tools of your choice. Do not copy the data folder between different versions of MYSQL or MariaDB. Databases from different versions of MYSQL or MariaDB are VERY unlikely to be compatible! You will also destroy the version of MYSQL or MariaDB that you copied the data folder to.
