Recover Local User Password

This option helps you to recover the password using SAM file. SAM file is a file that store Windows local accounts username and password in encrypted form.  

There are different methods to decrypt this file to retrieve the password. Sam file cannot be directly accessed when the computer is running or logged on. To import the SAM file, follow the following steps.

Run command prompt using administrative permissions.

Write these two commands to copy the SAM and SYSTEM file to the C: drive.

reg save HKLM\SAM C:\sam
reg save HKLM\SYSTEM C:\system

Running these two commands will copy SAM and SYSTEM file your local disk C.

Now browse to select the SAM file copied to the C: drive.

The software will read the SAM file and retrieve a list of user accounts.

Select the account name for which you want to recover the password and click “Recover Password” button.

Then select the method you want to use to recover your password. There are three methods supported for recovering the password.

Brute-Force Attack

Brute force attack is a method that is used to recover the password by making different combinations of letters, numbers, symbols, and special characters to find the correct password combination.

Typically it takes a long time when recovering long passwords as it may run millions of combinations to find the correct password.

Mask Attack

Mask attack is used when you know a portion of the password, say you have a password of 9 characters and you know last 4 characters as GRAM,  it’s useless to run a brute force attack for 9 characters combination in this case we will define 5 practice combination that will start from aaaaa to zzzzz and it will retrieve the password as INSTAGRAM

Make sure to enter a question mark symbol ( ? ) for all characters you don’t remember.

Dictionary Attack

In this method generates hundreds and thousands of dictionary words to find the password.

This dictionary is also made by software vendor with potential words of the password used worldwide.

Once you have selected the attack method, as in this case we have selected brute-force click next.

Now it will start finding that combination to decrypt the password and will show the results. 

For a faster process of retrieving forgotten passwords GPU is highly recommended on your computer, as the software will use GPU and CPU power combined to determine the password.

Without GPU it will work but it will work slowly and will take a very long time.

It will retrieve the password for the selected account. Click Exit to close the program.
