Add and alter the highlighted items to whatever admin pages you want to hide. This removes them for all users. For more flexibility and less coding, use a plugin.

function remove_admin_menu_items() {
 $remove_menu_items = array(__('Links'),__('Posts'),__('Comments'));
 global $menu;
 end ($menu);
 while (prev($menu)){
 $item = explode(' ',$menu[key($menu)][0]);
 if(in_array($item[0] != NULL?$item[0]:"" , $remove_menu_items)){
 unset($menu[key($menu)]);}
 }
 }
 
 add_action('admin_menu', 'remove_admin_menu_items');
