How to Reset Your Forotten Windows Password the Easy Way

Forgetting your password is never any fun, but luckily there’s a really easy way to reset the password. All you need is a copy of the Windows installation disk and one simple command line trick.

Resetting Your Forgotten Windows Password

Boot off the Windows disk and select the “Repair your computer” option from the lower left-hand corner.

Follow through until you get to the option to open the Command Prompt, which you’ll want to select.

First you’ll want to type in the following command to backup the original sticky keys file:

copy c:\windows\system32\sethc.exe c:\

Then you’ll copy the command prompt executable (cmd.exe) over top of the sticky keys executable:

copy c:\windows\system32\cmd.exe c:\windows\system32\sethc.exe

Now you can reboot the PC.

Resetting the Password

Once you get to the login screen, hit the Shift key 5 times, and you’ll see an administrator mode command prompt.

Now to reset the password—just type the following command, replacing the username and password with the combination you want:

net user geek MyNewPassword

That’s all there is to it. Now you can login.
Of course, you’ll probably want to put the original sethc.exe file back, which you can do by rebooting into the installation CD, opening the command prompt, and copying the c:\sethc.exe file back to c:\windows\system32\sethc.exe.

• How to make your passwords more secure

The technique we'll use contains a real life hack. We'll replace the Sticky Keys executable with a command prompt, so that even without logging in, we can pull up a command line and change the password, then use it to log in.
If you don't have a Windows installation disc, one option is to load up a password cracker. This is exactly what we'll do using the industry standard Ophcrack. You should only use these techniques to access your own PC. Hacking into another person's machine is a criminal offence.

Step-by-step: Recover Windows 7 passwords

1. Boot installation disc

To reset your Windows user account password, you must first boot the computer from the Windows 7 installation disc. Switch on your PC, and when you're given the option to boot from DVD, quickly hit any key to boot. After Windows loads its installation files, you'll be shown the language setup page. Select your country to set up the keyboard, then click the 'Next' button.
2. Repair the computer

Click 'Repair your computer'. The repair software takes a few moments to load from the installation disc, then begins examining the computer's hard disk boot table, looking for any current Windows 7 installations to repair. Unless you've installed many copies of the operating system by hand, there will be just one installation, so click 'Next' to continue the recovery process.
3. Find the C drive

The resulting screen gives you many options. Click 'Command prompt' and one appears. The C drive is usually not mounted as C at all, so you need to find out its current drive letter. To do this, type bcdedit | find "osdevice" into the command line. This command results in text ending in partition= and a drive letter. This is the letter you should use instead of C in the following step.
4. Prepare the recovery

Enter the following commands. Take care to ensure that you use the correct driver letter in place of C: copy c:\windows\system32\sethc.exe c:\ and copy c:\windows\system32\cmd.exe c:\windows\system32\sethc.exe. When prompted, confirm the second command by typing Yes. The first command backs up a file, and the second replaces it with the command prompt.
5. Reboot into Windows

Now remove the installation disc and reboot. On the login screen, press the [Shift] key five times in a row. As if by magic, a command prompt appears. Enter the following command: Net user <name> <new password>. Substitute the name of the account to reset and a new password as appropriate. Close the command prompt and enter the new password to log in.
6. Copy sethc.exe

The final step we must take to restore access is to restore the sethc.exe file we overwrote in step 4. To do so, click 'Start > Accessories', right-click 'Command prompt' and select 'Run as Administrator'. This gives you the right to copy sethc.exe back into the system32 folder. Now enter the command Copy c:\sethc.exe c:\windows\system32\sethc.exe. Confirm the copy to finish.
7. Download Ophcrack

To crack an unknown password, we need to use a heavy duty password cracker like Ophcrack. You'll need to download it from http://ophcrack.sourceforge.net/download.php. To get started, insert a blank, formatted DVD-RW, then right-click the downloaded image and select 'Burn disc image'. The disc being written is a bootable live CD containing both Linux and Ophcrack.
