How to break the lock of super administrators and ordinary users

Is it your computer? It's still your brother's.

Super administrators are also not allowed to view the passwords of ordinary users.

Brute force is required to unlock a user's password, whether it is an administrator's or a regular user's. The basic idea of practical feasibility is to pwdump out the windows sam, and then use the rainbow table to run out the plaintext of the password.

Another, slightly more ingenious way of thinking is to use GINA to record the password entered by the user when they log in.

So there is no one method that is effortless. If the password cannot be deduced, these two methods are not so feasible for the average user.

Generally speaking, the administrator account will not be locked, so it is recommended to change the name of this account to protect the security of the system.
