To use core_version_check_query_args filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at Flipper Code, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_core_version_check_query_args_defaults which takes 1 parameters and we registered using add_filter. The first parameter core_version_check_query_args is name of the hook, The second parameter modify_core_version_check_query_args_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_filter to remove core_version_check_query_args filter.
