Turning on the Administrator account is straightforward.
First, open an elevated command prompt by typing
cmd into the Search box on the Start menu, right-clicking
the command prompt icon that appears at the top of the
Start menu, then selecting Run as administrator .
Then enter this command and press Enter:
Net user administrator /active:yes
From now on, the Administrator account will appear as an
option on the Welcome screen, along with any user accounts
you may have set up. Use it like any other account. Be aware
that it won't have a password yet, so it's a good idea to set a
password for it.
If you want to disable the account and hide it, enter this
command at an elevated command prompt and press Enter:
Net user administrator /active:no
AutoLogon - Start - Search - netplwiz
Highlight User Name - Uncheck Users must enter a User Name and Password
Provide Password when prompted or hit enter if no password
