Hi,

  I cannot login to my Windows system. The previous user cannot remember the password he used, though the username is still there. I would appreciate any help as I need to retrieve important files from the computer.

   Thanks

Windows  Password Recovery

Try the following,

First: Are you sure you've forgotton it? Try just hitting return (in case there is no password), Then try all the password you would usually use
remember passwords are CaSe senSiTive so try with the caps lock on and off, or capitalise the first "Letter"

NB. All these tools, and links are to third party tools and involve directly or indirectly changing the registry. I accept no responsibility for their use.

Your passwords are held (encrypted) in the registry, and in your "restore" directory. These tools edit one or more of these locations from a boot disk

Arm yourself with a blank (clean) Floppy Disk

I've used this one on XP and it works

http://home.eunet.no/~pnordahl/ntpasswd/

Or try the following


----1----
This link will download software that creates a Linux Boot floppy that will let you change Passwords.

----2----

Using this link you will have to download the Image writer then the boot disk image

Easiest way if you have another computer with admin rights. Take the hard drive out and puit in the second PC as master. Take ownership of the files, and copy across. Rebuild machine. I am assuming that no - one else has an admin acvocunt on thew machine in question, as they could just reset it.
