Windows Action Center - what ID and password? How to set?

I just learned about the Windows Action Center, and I'm interested because of the feature to clone a VM. Clearly intended for IT professionals, but what the hey. I'm just Joe SixPack end-user.

So I downloaded it OK,and installed but, but I could not log in, because I couldn't enter a successful combination of userID and password. Any advice would be appreciated. I have no problem with using the registry editor, and I'm OK with PowerShell.
