How to hide or remove unwanted widgets on Multisite installation?

Question

I am using Multi-site installation. I don't want all the widgets appear under widgets.php on dashboard .So I tried to find a way to remove or hide unnecessary widgets . SO that the new sub-sites under my Multi-site created won't have much widgets. So the users don't get confuse with lot of widgets .

I tried to find the files related to widgets .But I didn't able to find such pages in both wp-admin/includes/widgets.php and wp-admin/widgets.php

I also tried to find in themes files .But failed .Could any one help me to find these ?

Or Do I have a chance to hide them using functions.php?

Thanks in advance !

Add this to your functions.php file:

function jpb_unregister_widgets(){
  unregister_widget('WP_Widget_Pages');
  unregister_widget('WP_Widget_Calendar');
  unregister_widget('WP_Widget_Archives');
  unregister_widget('WP_Widget_Links');
  unregister_widget('WP_Widget_Meta');
  unregister_widget('WP_Widget_Search');
  unregister_widget('WP_Widget_Text');
  unregister_widget('WP_Widget_Categories');
  unregister_widget('WP_Widget_Recent_Posts');
  unregister_widget('WP_Widget_Recent_Comments');
  unregister_widget('WP_Widget_RSS');
  unregister_widget('WP_Widget_Tag_Cloud');
  unregister_widget('WP_Nav_Menu_Widget');
}

add_action( 'widgets_init', 'jpb_unregister_widgets' );

This will get rid of all default widgets. If you want to keep a certain widget, remove that line from the function above.
