Stop. Using password tools, network penetration tools, and even network discovery tools on equipment and/or networks you don't own or have permission to access as an administrator is a crime in most of the United States. Prison and fines can be involved. Unlike what you read online, getting arrested for hacking does not lead you to the short path of high paying jobs in Internet Security. You were told.

Using HiRens to Reset Passwords

If you have not yet, download HiRens from Save the ISO file and then burn it to a CD. If you do not have or like your current CD burning software, try ISO Recorder from Alex Feinman.

Boot the computer you are working on to the HiRens CD. You may need to find the boot menu or change the BIOS to allow booting from CDs. When the computer boots, you may need to hit a key to boot from CD. Do so.

Boot Screen

From the Boot menu, choose Mini Windows XP. Yes, you want Mini Windows XP even if you are working on a Windows 7 or better computer. It will take a minute or so, but you will get a screen like this:

Welcome to HiRens. Click on the HBCD Menu icon. It has the little wrench on it. The menu doesn't look like much. Click on Programs and then Passwords and Keys and then, Windows Login. Choose NTPWEdit. Notice the path to the SAM file. Click on reopen. If you do not see a list of user names, use the file explorer to find the right drive letter for the hard drive of the computer you are working on. It is possible that HiRens has given a different drive letter to your hard drive than you were expecting. If so, change just the drive letter in the path to the SAM file and reopen again.

You should see a list of the users on the computer.

Click on the user name you want to change the password on. Enter a new password and save.

No Really, it is that simple.

Now reboot (HiRens has a Reboot and Eject option built in for you) and try out your new password.

Why would you need to do this?

  • Maybe you are in a workplace environment and someone has set a password and no longer works for the company. It happens.
  • Maybe your child changed their password (again) and forgot it (again).
  • Maybe you purchased a garage sale computer and it still has stuff on it.
  • Maybe you need the information off of your old computer that you don't use anymore and forgot.


  1. You probably are going to want to change the password on an Administrator account. The user of that account might notice the password has changed.
  2. If the user folder was encrypted by Microsoft, it is possible all of the documents will be lost if you change the password.
  3. This changes the password. It does not allow you to read the existing password.
