All of you must have seen the default administrator account in windows xp. By default it is hidden when you create a new administrator account of your own, but when you boot the system in safe mode you can view it on the login screen or in other words you can access it. The other way is that at the login screen press alt+ctrl+del for some time, you will get a dialog box to enter username and password and from there you can login into the admin account.
But this type of thing doesn’t happens in Windows 7, if you goto the cmd and type the command:
net user
You can view all the username on the system, there is an administrator account also, now the question arises if the administrator account is there then how to access it and where is it??
The answer is that by default the admin account in windows 7 is in deactivated mode, you have to activate it by yourself.
For activating goto command prompt and type the following command:
net user administrator /active:yes
After successful execution of this program you can view the administrator account on the login screen and can access it.
To again deactivate:
net user administrator /active:no
Note: These commands work in Administrator mode only/
