Question about Microsoft Windows XP Professional With Servise Pack 2 (e8503040) for PC
One method of gaining access to the system is by trying hard to remember the forgotten password, or a password of another user which has the same level of administrative rights. However I don't think this approach will help you, otherwise you wouldn't be sitting here reading article, would you?)
Another method is by trying to restore a backed up System State (in Windows 2000/XP/2003) or a ERD (in NT 4.0) in which you do remember the password. The problem with doing so is that you'll probably lose all of the recently add users and groups, and all the changed passwords for all of your users since the last backup was made.
A third method might be to install a parallel operating system on a different partition on the same computer, then use a simple trick to gain access to the old system. Read more about it on my Forgot the Administrator's Password? - Alternate Logon Trick article.
Note: If you are looking for password cracking tools that can be used for miscellaneous objectives such as password-protected PDF documents, zipped archives, Office documents, BIOS protection and so on then this pages is NOT for you. See some links at the bottom of this page for hints on where to find such tools, but I can tell you right away that Google might be a better choice for you.
The fourth option is by using 3rd party tools that will enable you to reset the lost password and logon with a blank password.
Update: You can also discuss these topics on the dedicated Petri.co.il Forgot Admin Password Forum.
Freeware Password Recovery Tools Here are some of these tools:
Free Windows password-cracking tools are usually Linux boot disks that have NT file system (NTFS) drivers and software that will read the registry and rewrite the password hashes for any account including the Administrators. This process requires physical access to the console and an available floppy drive but it works like a charm! I've done it myself several times with no glitch or problem whatsoever.
Beware!!! Resetting a user's or administrator's password on some systems (like Windows XP) might cause data loss, especially EFS-encrypted files and saved passwords from within Internet Explorer. To protect yourself against EFS-encrypted files loss you should always export your Private and Public key, along with the keys for the Recovery Agent user. Please read more about EFS on my What's EFS? page. Out of the following list, the only tool that will no cause any harm to EFS-encrypted files on your hard disk is the Windows Password recovery system.
Here are 5 of these free tools:
Important note for Windows Vista users: At this time there is only one solution for Window Vista and that is Petter Nordahl-Hagen's Offline NT Password & Registry Editor
Note: These password resetting tools are usually good for local users on a stand alone computer. For Domain Admin password resetting procedures please see the Related Articles section at the bottom of this page.
Note: I'd like to put together all the info you have about these issues. If you have any tips, recommended links or any ideas about how to figure out a lost password - please e-mail me and I'll get back to you .
Windows Password recovery http://www.loginrecovery.com
This site provides a tool to recover lost Windows XP passwords. It works for administrator and user accounts, it doesn't change the password just tells you the old one. It works with encrypted files (EFS) and password hashes. It even works if no passwords at all are known for the machine (as long as you have another computer with internet access to view this website with).
Author claims it also works with Windows NT and Windows Server 2003 and Windows Longhorn, but the BEST thing about it is the fact that it won't reset your passwords, but simply reveal them for you to remember and then use.
Give it a try. The author would like to receive feedback. There is a free service as well as a priority service that will retrieve your passwords within minutes. The fee for the priority service is very cheap, and is really just to cover server costs.
Note: You'll need a blank floppy to run the process.
Update: Author now offers the same tool as a CD image for those of you who do not have a floppy in their computer.
