It’s not available as an option from wp-admin.
It’s possible with some fairly advanced coding – you’d need to be a competent PHP developer:
You could look at using the  wp_set_auth_cookie() to auto login the user on registration.
You need to hook on to an appropriate action in the user registration process – disable the call to wp_new_user_notification(), and then use the auto login function above.
Alternatively, you could have a look to see if there are any ‘off the shelf’ plugins to do this for you — I’m not aware of any.

		A simple google search shows that
wp_new_user_notification is in wp-includes/pluggable.php
