Using Ophcrack can be a useful option for recovering your Windows 10 password if you don’t have access to another admin account or a Windows recovery disc. However, it may not work for all passwords, and it can be a time-consuming process. If Ophcrack does not work for you, there are other methods available, such as using a Linux-based USB drive to change the SAM file and bypass the Windows password, which will be discussed in the next chapter.

Method 4: Using a Linux-based USB Drive to Change the SAM File and Bypass Windows Passwords

The SAM (Security Accounts Manager) file is a database containing user account and password information for Windows operating systems. By modifying this file, it is possible to bypass the Windows login screen and gain access to a computer. One way to do this is by using a Linux-based USB drive.

Step 1: First, download and install a Linux operating system on a USB drive. This can be done using various software such as Rufus or UNetbootin.

Step 2: Once the Linux operating system is installed on the USB drive, insert it into the computer that needs to be accessed.

Step 3: Boot the computer from the USB drive by changing the boot order in the BIOS settings. This can usually be accessed by pressing the Delete or F2 key during startup.

Step 4: Once the computer is booted from the USB drive, navigate to the location of the SAM file. This file is usually located in the “Windows\system32\config” directory.

Step 5: Rename the SAM file to “SAM.bak” to create a backup of the original file.

Step 6: Now, locate the “system” file in the same directory and rename it to “system.bak“. This file contains the password encryption key.

Step 7: Rename the backup files to “system” and “SAM” respectively. This will restore the original files after they have been modified.

Step 8: Next, use a Linux text editor such as vi to open the SAM file for editing.

Step 9: Search for the username of the account whose password you want to bypass. The password should be located next to the username, enclosed in quotation marks.

Step 10: Delete the encrypted password and replace it with * or ! to create a blank password. This will allow you to log in without needing a password.

Step 11: Save the modified SAM file and exit the text editor.

Step 12: Remove the USB drive and restart the computer. You should now be able to log in without a password.

Note: This method only works for local accounts and not Microsoft accounts. Also, it may not work for newer versions of Windows as the SAM file is better protected.
