Is there a Linux app to reset password?

This is for a Win 7 Acer pc.

Answer to the question

Offline NT Password Editor is out of update for years. You can reset lost password using just your Windows install CD:

1. Start your PC off the Windows install CD

2. Once loaded, press Shift+F10. This will open a command prompt

3. Run the following commands in order:

    diskpart
    list vol

4. Once you find the right volume (your C: drive (it may have a different drive letter)), run exit

5. Now, run D: where D is your drive letter.

6. Run cd \Windows\System32

7. Run ren Utilman.exe Utilman_old.exe

8. Run copy cmd.exe Utilman.exe

9. Reboot

Once you get to the logon screen, click the Accessibility Options icon. Once the Command Prompt opens, run these commands, replacing user_to_change with the user you want to reset the password of:

net user user_to_change *

Enter a new password, enter it again (you won't see it) and log in. You can now go back to C:\Windows\System32 and delete the Utilman.exe that we made, and rename Utilman_old.exe to Utilman.exe. With this method you can reset Windows password for any computer. Remember to set a new but easy-to-remember password after you're in.

This works on a Deb based version of Linux, such as Ubuntu

There is different method for RPM versions of Linux, such as Fedora
