#1 Disable all default WordPress widgets

If you create a theme where widgets are not used, you can disconnect them so they don't get in the way.

remove_action( 'init', 'wp_widgets_init', 1 );

When adding this code, it is important to keep in mind that the widgets_init hook will also stop working, because it is called from a function whose call we undid.
