Jes, just to be confirmed, are you using the Windows Installer package?
or is it standalone installation where you have installed XAMPP and installing Moodle over it?

In case of Windows Installer Package, everything comes pre-set, means database and PHP ready to run moodle with configurations settings already in place.

Regarding config.php file, if you go into SERVER > MOODLE folder, you'll find config.php file there, for MySQL the port number used is 3306.

If the screen has turned blank at some point, it usually occurs when cache's get corrupted (usually happens with local moodle installation off of windows installer package), for that go into SERVER > MOODLEDATA and you'll find two folders there "cache" and "localcache", just delete them both and refresh the browser, it will re-create folders and Moodle installation will work fine.

Jes, your problem is evident, the default port for web server "80" is being used by something else, could be installation of IIS on your machine, could be SQL Server Reporting services or even Skype.

Now tell me, which ones of these are you using? usually its Installation of IIS on the machine that results in ports being used.

Now assuming, you are using IIS as well, you can either uninstall IIS for the port to be freed up for Apache's usage, else you can change the listening port on apache, so something like 8080, that way you'll be opening your site to be served by apache by typing http://localhost:8080

which way do you want to proceed?

Ilaria, forgotten passwords works just like if you have forgotten password for your web based email. So in case of password recovery, student will be sent a temporary password to his/her email to log-in Moodle and from there student can change his/her password once again, but by no chance they will be getting exact same password that was on account before.

Anderson, the built in players within Moodle arent capable of responsive behavior, only possible way to achieve this is using JWPlayer (though there is moodle plug-in for JWPlayer, but that isn't even capable of responsive attitude).

Using JWPlayer, you wont be uploading files into your Moodle, but maintaining a separate directory, this way linking videos within moodle, and the player will adjust its width and height as per user's screen.

Alternatively, mention height and width that is considered averagely used, this is a big mistake in designing on the basis of what my screen looks like, still many people are on 1280 wide screen, with 1366 catching up fast. So when embedding video, adjust your browser to a lower window size so you can have idea of how your site will look like at average user's end.
