Cracking the XP Administrator Password

1. If you run the doscommand, use the XP installation disk to start to the fault recovery platform, use the net user username to add and delete new users, change passwords, and increase permissions. In command mode, run
Net /?
Add a new user: Net user DDD 123/Add
Ddd is the user name and 123 is the password
Raise DDD to the Administrator group: Net localgroup administrators DDD/Add

2. Run "Net user administrator" in % SystemRoot %/system32/drivers. After successful execution, the administrator password is also cleared. Close cmd or explorer and log on with a blank password. In fact, this method is consistent with the above idea.
3. Download the password modification tool. For details, we recommend erd2003. After downloading the tool, it is converted into a boot disc and started with a disc. entering its desktop is similar to XP, start-Modify the password (you can force the change without entering the original password), and then restart.
Do not delete the Sam file.
