Hello,

One of my users has a windows 7 laptop that is not on a domain.  This user decided to change the admin password and they forgot what they changed it too.  Whats worse is that this was the only user id on the laptop.  I do have physical access to the laptop.  Is there any way to reset the password?  Maybe something like winternals for Windows 7?

Easiest way is to do a System Restore (as long as the user can remember the old Admin password).

http://www.sevenforums.com/tutorials/700-system-restore.html

This will obviously restore the Admin password back to it's old one, as long as you restore to a point before the password was changed. Just bear in mind it will undo any changes that have been made, although if the password has just been changed recently, that shouldnt be an issue.

There are other ways of hacking a file/reg key to change the password, but this first method is easier.

I thought of the restore but my user changed the password months ago....used the laptop for a few weeks....made a lot of changes.....and then put it on a shelf.  Any other recommendations besides a kick in the a$$

I'm not in this for points but I recommend you go with the_scotsman's advice burn that sucker to a disk and just follow the prompts when you boot from the cd.

it's a lot of text but don't let it scare you, usually you can just go with the defaults. when it's done it will ask you to write the changes, hit  yes and you are golden.

Either use Offline NT Password & Registry editor http://pogostick.net/~pnh/ntpasswd/

or

Ophcrack http://ophcrack.sourceforge.net/

Personally I use Offline but it is your choise both are able to help you.

I would definately use Ophcrack (Live CD) from http://ophcrack.sourceforge.net

But after you have used it, destroy the CD or lock it away safely cause it can be used exactly the way you are going to use it. very dangerous in wrong hands
