● Minimum password length determines the strategy of the length of a password, valid values ​​in between 0 and 14. If set to 0, then no password, which is the default value of the system, and from a security perspective, allowing the user without a password is very dangerous there.

Specific methods as follows.

open the it plain to the Administrator to reset a user name. Then create a name for the Administrator of the restricted users to confuse intruders.

The only solution is to enter safe mode, then the hidden Administrator user will appear in the user selection list, the default password is blank, how? Enough to risk it! With the Administrator user login,Windows 7 Pro Product Key, although there is no way to delete this user can not change your username, but you can with a complex password, more than 12 irregular almost impossible to crack the password, up with it.
