do you know the old password?? don't worry,Repair through System Restore on Windows Vista DVD,Just pop in the Vista DVD, make sure your BIOS is able to boot from DVD-ROM first.select Repair your computer, select the operating system that you want to repair,then System Restore, select restore point that was a day before you changed the password, and then click Next.
Doing this will set your computer back in time to the particular date when it was working fine. When the System Restore process is complete, hit Restart computer.After the computer restarts, click Close to confirm that the System Restore process has finished successfully. After you log on with the old password, change the password for the administrator account if you like.

the best thing is format the laptop with the Dell Recovery option since you lost contact of the previous user. Insert the Dell Windows setup disk supplied with the system, select the "Repair My Computer" option. go back to 'factory defaults' and try again to set a password. Also set a 'reminder' and create a 'password reset disk' from the User Accounts options
