While I can't retrieve the passwords I can change the administrator account with NTPASSWD (see google) and log on with that account to change all the other passwords.
Is that good enough? (it's free too.)
I have a PC that was donated to our church. I plan to upgrade the memory and add some software to give it to a needy family. The problem is there are users set up and I do not have the administrators passwword.
How can I get a users password from this PC?
