6) Remove wp_head
By default,WordPress executes the wp_generator() function whenever the wp_head() hook is called. Typically, this hook is located in your theme’s header.php file with in the <head> section of the document markup. Removing this hook from your header.php file might break other functions/plugins on your site which rely on this hook. So you should not do this way.
