#3 How to Crack Windows 7 Admin Password with Hash Suite

Hash Suite is another great option when it comes to cracking Windows 7 admin password. What sets it apart from the two method listed above is that it generates multiple hashes to store your passwords and then compare the computed hashes with the stored hashes.

To create those hashes, the tool uses a number of different ways, including Charset, Wordlist, Keyboard, Phrases, DB Info, LM2NT. All of them behave the same as the attack modes do. The tool supports all Windows versions, but we are going to stick to Windows 7 in this guide.

Hash Suit now offers both free and paid versions. The Standard Suite costs $39 for a lifetime license that unlocks many of its premium features. The free version includes the ability to crack Windows 7 password (short password only). If you want to crack a long, complex password, then we recommend you go for the Standard version.

Download Hash Suite

Step 1: First off, you need to obtain hashes. To do this, you can use hashes from the public demo (available at here). This list includes all publicly available hashes of common passwords.

Step 2: Open the Hash Suite on your computer and import the list.

Step 3: Now crack your password using word lists. To do this, we are going to use word lists with the file named Wikipedia-wordlist-sraveau-20090325.txt.bz2.

In this case, we’ll use the Charset key-provider with default options, which are: password length from 0 to 6 with all printable characters. (image below)

#4 Crack Windows 7 Password via L0phtcrack

L0phtCrack made its debut back in 1997, allowing users to crack an eight-character Windows password within 24 hours. Using L0phtCrack does not require any technical knowledge, but there are many who encounter problems with this password cracking tool. If you are a newcomer, then make sure you follow our guide.

If you are running the software for the first time, you are going through an initial setup. From the first menu, hit the Next button and check the box next to the Don’t show me this wizard on start up option.

Next up, if you want to retrieve your lost password from a local admin account, simply select the “Retrieve from the local machine” option and then click the Next button. On the next window, select your auditing method you prefer.

Once you are done, pick your reporting style. We recommend you tick all the options and then you will be presented with a list of all user accounts that are linked to your Windows. Select the one you wish to reset the password for and the cracking password process should begin.

My Takeaway

The security feature of Windows 7 is not as strong as Windows 10. This makes cracking Windows 7 password much easier and a lot of free and paid tools can help you achieve the goal. If you forgot Windows 7 password and want to crack it by yourself, please try Ophcrack first, which is free and powerful enough for weak password.

However, if the password could not be cracked by Ophcrack, then switch to PassMoz LabWin, which will get your computer unlocked in minutes no longer how strong the password is!
