Adding lucrative things in your website will add value to it for a longer time, then why not opt for it, if it is an easy task to achieve.

To display recently registered users, simply paste the following code below at the place where you want to display recent registered users.

<ul class="recently-user">
    <?php $usernames = $wpdb->get_results("SELECT user_nicename, user_url FROM $wpdb->users ORDER BY ID DESC LIMIT 5");
        foreach ($usernames as $username) {
                echo '<li>' .get_avatar($username->comment_author_email, 45).'<a href="'.$username->user_url.'">'.$username->user_nicename."</a></li>";
        }
    ?>
</ul>

<?php $usernames = $wpdb->get_results("SELECT user_nicename, user_url FROM $wpdb->users ORDER BY ID DESC LIMIT 5");

foreach ($usernames as $username) {

echo '<li>' .get_avatar($username->comment_author_email, 45).'<a href="'.$username->user_url.'">'.$username->user_nicename."</a></li>";

</ul>
