How can I change the Administrator for Windows 8.1?

How do I access the Adminstator file to make a change?

If it is your computer, you should already be using an Admin account.

Right click on the far left Windows icon in the Taskbar > select Control Panel > All Control Panel Items > User Accounts > what does your account say there?

@@@@@@@@@@@@@@@@@@@@@@@

There is this hidden account, but do NOT run it for everyday use.

If you do that, you jeopardize the security of your system.
