Ophcrack is a password cracking tool for Windows PCs and it is based on rainbow tables. What this tool does is it lets you recover the forgotten passwords for the user accounts on your Windows computer.
When you have forgotten the password of an account on your PC, you cannot gain access to the files stored on that account which means there is no way for you to get access to the important files you have saved in that account.
If you have only have a single account on your PC and you have forgotten the password of that account, it means your entire PC is blocked and you have access to nowhere. In such a situation, you can't even run an app to recover the password as you just don't have access to your PC's interface.
That's the reason Ophcrack offers a Live CD solution. You just have to burn their disk image onto a CD and you can then boot up your PC from it and follow the on-screen instructions to regain access to your account. Here's how to download and use Ophcrack on Windows 10.
Although Ophcrack has been around for a long time, it is not compatible with Windows 10 well. Windows Password Key, the best Ophcrack alternative, can easily forgotten Windows administrator/user password and Microsoft account password for Windows 10/8.1/8/7/Vista/XP. Similar to Ophcrack, this app also allows you to write a recovery disk on a CD, a DVD, or a USB drive. Once you have created the disk, you can use it to boot your PC from and you should be good to go with recovering the forgotten passwords.
