Until recently I have been getting assistance with my Windows Vista
Ultimate through an IM connection, with a file sharing port open
between us. I would now like to change the passwords and close all
access ports to my machine. How do I go about doing that?
Petter Nordahl-Hagen's Offline NT Password & Registry Editor
This is absolutely one of the best free tools to reset the administrator
password and gain access that I have ever used. It modifies the encrypted
password in the registry's SAM file allowing you access to the account in
Windows NT/2000/XP/2003/Vista systems.
There is an image file to create a bootable floppy disk or bootable CD to
modify the admin password and access NTFS partitions. You do not need to
know the old password to set a new one. It will also offer to unlock
disabled or locked user accounts (a very helpful feature). The program was
just updated on April 9, 2007 to include Vista support.
Please visit the site by clicking on the link below to download a CD image
or floppy image of this great program.

Another option is to decrypt the password and show you the actual
administrator password. A great site for doing this is loginrecovery.com.
Basically, you download a small program to extract the password from the
computer, then you submit the encrypted password file to their site and they
will recover the lost password. Of course, you need a computer with Internet
access to upload the file and find the password.
With this option, the administrator password is not changed so you wont lose
access to EFS encrypted files. Visit their site by clicking below

Although there are probably other options to recover an administrator
password, I find the two option shown above to be the quickest and easiest
ways to either change or discover the password and allow you access to the
user profile and data stored on the hard drive.
