Thread: Locked Win 7 PC

  1. #1

    Default Locked Win 7 PC


    It is my dad's PC powered by Windows 7 and has been with him for years. I bought him a new Dell laptop a few months ago and unfortunately he forgot the admin password of old Win 7. Now he asked me to unlock the device but I don't have any clue except reinstall.

    Could some one shed lights on this?

    Does he have any accounts on the machine that he remembers the password for?

    Also, have a look at this article: https://www.recoverywindowspassword....n-windows.html

    Windows 7, you say? You can unlock the account if you have a copy of MSDaRT

    The flavor (x64 / x86) is important, as it reads the SAM's.

    Well, Another option (If you haven't fixed the issue) is Hiren's Boot CD. On his Mini XP there's a tool that will reset passwords on the machine. But you do have to mount it on a flash drive or cd to use it (and there's plenty of documentation for that).

    I only know how to use version 15.2, but fans have made a new environment using windows 10. And use it at your own risk (You can do some damage...)

    Windows stores passwords in the SAM registry hive using one-way hash. This is located at %WinDir%\system32\config\sam. If you are not an admin, you can not access this. It is vulnerable to offline attacks like password recoveries/password deletions.

    is what I use. It is also free and open source. It is command line based..but it doesn't "recover" your password..but rather deletes the password completely. I've used it a lot on people's computers. Because it doesn't attempt to recover the password, it's pretty fast and efficient.

    It is explanatory as long as you know how to boot from a CD and can read.

    There are, of course, other options..But that is the one I use.

    Good luck.

    Worked for me.

    Of course, this is the Win10 version. Is your machine set up for booting to USB/CD? I'd try the UUSB Installer to write it to a ~4 GB USB flash drive if you have the ability to boot to flash. Otherwise, what Ric posted is another viable solution.

    EDIT: Tried it on my Win7x64 host in my ESXi server. Worked there as well.

    Update this thread. A lot of people here took their time to help you.

    Do you still have the same issue? Don't be a dick.

    You'll regret it if you do,there are many good ways to break your password without having to install a system.
