At present,as Windows 10 occupies a large market,there will be a lot of tutorials on unlocking Windos 10 password,like this guide.In any case,here is how to crack Windows 10/8/7 passwords,and the Ophcrack is also a good password cracking tool.

In recent blogs, I've demonstrated how to grab password hashes remotely using Metasploit's meterpreter and pwdump. Once we have the Windows passwords from the SAM file, we can then crack these hashes using tools such as Cain and Abel.
In this article, we'll look at how to grab the password hashes from a Linux system and crack the hashes using probably the most widely used password cracking tool out there, John the Ripper.
I've purposely chosen dictionary words as the complexity of the password is inversely related to the time necessary to crack it. One of the nice features of John the Ripper is that it will try to use a dictionary attack first. If that fails, it will try a hybrid attack. And only if that fails will it attempt a brute-force attack, which is the most time consuming.
Now that we have a couple of regular users in our system with simple passwords, we now need to open John the Ripper. John the Ripper is a simple, but powerful password cracker without a GUI (this helps to make it faster as GUIs consume resources).
We can access it from BackTrack by going to the BackTrack button on the bottom left, then Backtrack, Privilege Escalation, Password Attacks, Offline Attacks, and finally select John the Ripper from the multiple password cracking tools available.
John the Ripper will proceed to attempt to crack your passwords. As you can see, it cracked all three of ours in a matter of seconds! Of course, more complex passwords will take significantly more time, but all we need is just one user with a simple password and we have access to the account in seconds.
It's also important to note that any password cracker is only as good as its word list. For more complex or hybrid passwords, you probably want to use a password list containing far more passwords, including hybrid passwords such "p@$$w0rd" that combine special characters into words.
John the Ripper does come with a word list built-in, but if you are trying to crack more obscure passwords or passwords in a different language, you will need a different word list. Simply googling "password list" or similar key words will provide you with many word lists, some with millions of entries.
/etc/shadow is where the password hashes reside. /etc/passwd has all the users details but not the hashes. We need both to crack the hashes. unshadow gives us access to the hashes and combines the info from those two files to make the hashes available to john.
This article is meant to demonstrate the principles of password cracking in Linux. Rather than going into the many ways that a non-privileged users can get root access, this article focuses on what to do when you get it. When one does get root access and the /etc/shadow file, you still have to crack the hashes with John or other cracking tool. 2ff7e9595c
