Now, I don't know how to start mariadb since I didn't install it as a running service.
This didn't help me:
I googled and thought this would work to set it as a service:
C:\Program Files\MariaDB 10.0\bin>mysql_install_db.exe --datadir=c:\mariadb --service=MyDB --password=secret
Removing default user
Setting root password
Creating my.ini file
Registering service 'MyDB'
FATAL ERROR: OpenSCManager failed (5)

Here's what you do.
cd C:\Program Files\MariaDB 10.0\bin
That sequence of operations should remove the service and then install it. Finally it will start it. If you don't use a shell in Administrator mode, this won't work.
You can double check this is right by closing, reopening, and looking at the Services app in the Microsoft Management Console.
