Enabling Administrator Account in Windows 7
In Windows 7, like Windows Vista, when you install the operating system, you are asked to enter a user name which will be the primary local user that will use this system.
Like in Windows Vista, in Windows 7 the built-in Administrator's account is disabled by default. Furthermore, this account is not associated with any password
The new user which is created during the installation is configured to be a member of the built-in Administrators group, and in fact, can be used for any management task. That use is in fact equivalent by all means with the original built-in Administrator account.
However, there may be situations where one would like to use the built-in Administrator account instead of that "new" user. One of these might be when you're building a system for cloning purposes, and would like all cloned machines to be able to use the built-in Administrator's account.
Note that since that account does NOT have a password, enabling it without properly setting a password for that account will open a serious security opening on your system!
To enable the built-in Administrator's account by using the Local Users and Groups snap-in please follow these steps:
Open Local Users and Groups. You can do so by typing lusrmgr.msc in the Start search box or in the Run command and pressing ENTER. Or, you could open Computer Management by right-clicking Computer in the Start menu and selecting Manage.
Expand System Tools > Local Users and Groups > Users.
Right-click the Administrator account and select "Set Password
In the"Set Password for Administrator" click "Proceed".
In the"Set Password for Administrator" enter the Administrator's desired password twice, and click "Ok".
Next, enable the Administrator's account. Right-click the Administrator's account and select "Properties".
Un-chek the "Account is disabled" check-box. Click on the "Ok" button.
Administrator's account is now enabled and configured with a password.
