Enabling Admin Account on 7

When I want to install 3dsmax, it said that I don't have sufficient priviledge to do it. The first thing that come to my mind is,"I need to access as administrator". Then after doing some research, I found these steps…

Enable Built-In Administrator Account

1. Open the command prompt, run as administrator

2. Then, type the following command and press enter.

net user administrator /active:yes

now, log out your current account and you'll find this in log on screen.

Disable Built-In Administrator Account

you need to log in as any account except administrator, then type the following command and press enter :

net user administrator /active: no

You won't see administrator account showed in the log on screen anymore...
