I have already seen http://dev.mysql.com/doc/refman/4.1/en/mysql-config-wizard-file-location.html
how to know mysql my.cnf location
and
http://dev.
Press the windows key > type services > press enter > Look up mysql in the list > right click > properties > Path to Executable will have the location of the defaults file right below it (my.ini)
You can find the my.ini file in windows at this location- C:\ProgramData\MySQL\MySQL Server 5.6
the ProgramData folder is a hidden folder, so make the according setting to see that folder. And open my.ini file as an administrator to edit and then save that.
