Ophrcrack can crack th vista logon password. Does this box come on before the BIOS/POST screen, so you don't see Vista load? If it does its probably a BIOS password. To get rid of it you can remove the BIOS battery or find out the default password for the BIOS you have, which doesn't look like an option.
So you'll need to take out the battery.
the above one ophrcrack is also used for cracking windows.

where here are some other cracking tools
Password Recovery 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 tools:
- SpotMau Password Finder - Simple startup utility resets a forgotten admin or users' password using a familiar Windows-like program interface instead of command-line.
- Password Kit - Top rated version of Passware's Password recovery app, supports Windows Vista and RAID/SCSI/SATA drives.
- Petter Nordahl-Hagen's Offline NT Password & Registry Editor - A great boot CD/Floppy that can reset the local administrator's password.
- Openwall's John the Ripper - Good boot floppy with cracking capabilities.
- EBCD – Emergency Boot CD - Bootable CD, intended for system recovery in the case of software or hardware faults.
If you happen to know about other
free tools
please let me know.
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.
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
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. The fee for the 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. Usage, instructions and additional information can be found at

Offline NT Password & Registry Editor (v080526 - May 2008)
Petter Nordahl-Hagen has written a Windows NT/2000/XP/Vista offline password editor:
home.eunet.no/pnordahl/ntpasswd/
- This is a utility to (re)set the password of any user that has a valid (local) account on your Windows NT/2000/XP/2003/Vista system, by modifying the encrypted password in the registry's SAM file.
- You do not need to know the old password to set a new one.
- It works offline, that is, you have to shutdown your computer and boot off a floppy disk or CD. The boot-disk includes stuff to access NTFS partitions and scripts to glue the whole thing together.
- Works with syskey (no need to turn it off, but you can if you have lost the key)
- Will detect and offer to unlock locked or disabled out user accounts!
