How To Unlock Your Computer After Forgetting Your Windows Login

If you forget this you will be locked out of your account and unable to access all of the files and software specifically tied to that account.


Unlocking your computer won’t be easy, but it is possible. Let’s take a look at how you can access your system even if the login has been forgotten.


Resetting Your Windows Login Password – The Super Legit Way

Windows has a built-in password reset feature. It would be rather pointless if anyone could reset it, so you have to do the preparation before you forget your login if you want to be able to use this feature. This consists of creating a password recovery disk, which can be any removable USB drive or even a floppy disk. Please note the instructions here apply to Windows Vista/7.

To begin, do a Windows Search for Password Reset Disk. You should see “Create a password reset disk” as your first option. Select it.


This will open the Forgotten Password Wizard. The introductory screen explains the basics, and once you’ve read it, click next. Here you can select the disk that you want to use for password recovery. Since only removable drives can be used, only they will appear as an option. Select a drive and click next.

On the next screen you will have to enter your current password. Do this and click next to begin creation of the password recovery disk. This will likely be a fast progress – it literally took five seconds on my PC. And you’re done.

Resetting your Windows login is now easy as pie. Just click the “reset password” link below the login screen and follow the on-screen steps. You’ll have to select the appropriate disk and then enter a new password. Presto! Your computer is unlocked.


Resetting Your Windows Password – The Not-So-Legit Way

Using the password reset disk is just fine if you have prepared beforehand, but if you are reading this article, I’d say there is a fair chance that you didn’t. I don’t blame you. Windows doesn’t remind users to create a reset disk.

If you are locked out of Windows without the legitimate recovery option you will have to turn to a third-party password cracking tool. The best free option is Ophcrack Ophcrack - A Password Hack Tool to Crack Almost Any Windows Password There are a lot of different reasons why one would want to use any number of password hack tools to hack a Windows password. Read More , a tool which uses something called a “rainbow table” to guess your password.

To use Ophcrack, you must download the .ISO and then burn it to a CD. This creates a live cd that you can boot from. Most computers are set to boot from any bootable CD by default, but you may need to change your BIOS options so that your optical drive is first in your boot order. There are separate versions for Windows XP and Windows Vista (the Vista version should work with Windows 7) so make sure you download the correct one.

Once you boot via the Ophcrack Live CD you need to select a mode. The default is “automatic” and that is what you should generally use. The software will run through several more steps, which include black screens with running lines of text, before entering into the Ophcrack menu and beginning the cracking process. Don’t be alarmed – things are working as intended. Once a password is cracked it appear in the right-hand column on the main window.

There are some severe limitations to what this tool can do. Ophcrack won’t work against strong passwords that use many random characters – particularly if you are trying to crack a Vista/7 password. The cracking process can take some time, as well, depending on the password you are trying to crack. Simple passwords tend to be quick – complex passwords take more time.

Another problem is lack of support. There aren’t many solutions if you run into a bug or error, and since the software runs by booting into a Linux environment, troubleshooting can be particularly tough if you don’t know much about Linux (like me). If you are running in to any problems with the tool, try Ophcrack’s FAQ wiki page.



These methods can work, but they’re not perfect. Recovering your Windows password via the legitimate method requires preparation. Ophcrack, on the other hand, is open source software with poor support that has difficulty with complex passwords.

If you used a complex password on a Windows Vista/7 machine you may be out of luck. This means you may need to reinstall Windows. Don’t forget to recover your files before you reinstall.

    I also want to unlock my computer login password because I forgot it, and finally I use the Windows Password Key to solve my problem. It has 3 versions and I use the Professional version. I get it from CNET. It is so helpful. You the guys can search more about it.

    I am trying to sort out my dell computer as my ex has messed it all up just to put a portable hard drive in. Now it is saying I need that hard drive as it can not locate floppy disc 5. I cannot get pass the screen that comes up first. All the passwords I would have used do not work so how can you set a a reset password disc if you need that password which is the one you have forgot!

    I normally use ERD Commander or MSDART to reset the password. A lot of people have passworded administrator accounts or decided to use that as their primary account and that method won't work. I've also used ntpasswd with some luck

    LOL all this to reset a password. Just boot into safe mode and unlock the admin account. Or if you really want to get wild take a loot at the NT offline password changer...

    You can boot to a free program called Kon-Boot which will create a temporary admin account. From there you can reset the password if you wish. If you are using Window's built in encryption on some of your files, use FTK Imager and copy the system files and move them to another machine to begin recover. There are a variety of tools available to recover the passwords from the SAM and SYSTEM files. If your password is recoverable with a rainbow table, your password is way too short and simple. 8 characters and letters and numbers are no good these days. Also, any means of recovering your own data is "legit".

    You can also use a Linux Live USB to mount your system drive, make a copy of cmd.exe, back up utilman.exe, the Windows accessibility tools available w/ CMD+U on login screen w/out entering a password, then rename cmd.exe to utilman.exe. Now you can use CMD+U to bring up a command prompt without logging in, and from there you can reset the admin password.

      yes - We can simply boot in safe mode (press F8 before windows start booting up and select safe mode) when we can login to an alternate administrator account with which we can remove the password on any account (including other admin accounts) - Windows is really weak when it comes to login security. And I tried this on several different computers including windows xp and windows 7 adn it always worked like a charm :-??

        A well secured Windows box will be defended against this, as mine was when this happened to me. Trinty Rescue Kit was the only thing I found that worked.

      Yep. But you do need a second admin account you know the password to (or is not password protected).
