Search for a password from the SAM File
Use special software to find the logon password from the SAM file of the local system or remote system using the password dictionary or brute-force cracking method. This method can identify the password of the original user name. However, it may take a long time depending on the machine performance.
This type of software is well known as L0phtCrack (LC), LCP, and SamInside pro. The three software must have the Administrator permission before installation. If you do not have the Administrator permission (the logon password is lost ), how to install it? You can use DreamPackPL for Windows installation, or use Bart PE or Windows PE to start running software. However, L0phtCrack (LC) cannot run in this environment.
Advantage: it is important to encrypt data with EFS without damaging the original system password.
Disadvantage: slow speed may take days or even years.
The following describes how to use the software.
