Remove / Rename Uncategorized Category In WordPress

I have installed wordpress Muilit Site (NETWORK)

I need to Remove / Rename Uncategorized Category In WordPress.

How is this possible?

To change the default “Uncategorized” using code you can do the following:

// Uncategorized ID is always 1
wp_update_term(1, 'category', array(
  'name' => 'hello',
  'slug' => 'hello', 
  'description' => 'hi'
));
