I had to enable administrator account using the following command - "net user administrator active:yes" and then the same thing but use "no" to disable the admin account after I was done using it. I also deleted Administrator account from Account options in Control Panel and deleted Administrator folder is Users folder. All seems good and I auto-login to my proper user-admin account now, BUT if I sign-out, then Administrator account option is still there. How do I completely remove it from, being listed on the sign-in/out screen?
