How to deactivate the automatic emails sent to administrator? Is there any existing module to edit automatic emails sent to admin by Drupal 7? 
Something like Mail Editor to edit the mail templates but not only for those sent to users. 

I need to deactivate the automatic email sent to administrator when an user have created an account. I have created a Rule to have details on this new account with tokens and now I do not need the automatic core email anymore.

Thanks for any help. I can not find any solution to this, except this custom module and I would prefer a newbie solution.
Enable and Install the Mailcontrol module and then go to admin/config/people/accounts turn off the checkbox.


  This small module extends original Drupal 7 account settings page with
  the ability to globally turn ON/OFF all standard mails.


By default Drupal 7 provides no option to globally disable the following mails:


Welcome (new user created by administrator)
Welcome (awaiting approval)
Welcome (no approval required)
Password recovery
