Hi Rebekah,

It's possible that you're not using an elevated command prompt, causing the Access Denied error. We suggest following these steps to properly disable the built-in administrator account:

• Right-click the Start button.
• Choose Command Prompt (Admin).
• Copy and paste net user Administrator /active:no and press
  Enter. If the command isn't successful, please post a screenshot so that we can study it further.

Let us know if you're able to hide the administrator account after following these steps.
