As a basic first security measure, we recommend you change the name of the Administrator account on a Cloud Server with Windows 2016. The Administrator user is the default user for all Windows accounts, and thus is frequently the target of brute-force password attempts. Changing the user name is an easy way to provide a higher level of security for your new server.


  • A Cloud Server running Windows 2016.
  • The root password and IP address or domain name for the server. To find this information, log into the 1&1 Cloud Panel and select the server on the Servers section.
  • The instructions in this tutorial are designed for a Windows 10 desktop. The specific instructions for other Windows versions may vary slightly.
