If you haven't made a password reset disk before computer is locked by a forgotten Windows password or don't have an available admin account to access to Windows to reset Windows 7 admin password, maybe the only easy way for you to reset password is using the third-party software. Look the following four software I list and see how they reset forgotten Windows 7 password.
Ophcrack: it is by far one of the best available free Windows 7 admin password reset tools online. It takes time to burn the free ISO image to a CD on its site and then use the bootable CD to remove the forgotten password without accessing to Windows. The program only can reset the passwords that less than 14 characters in Windows 7, Vista and XP.
Kon-Boot: it also can free recover Windows 7 admin password. You need to burn the program to a disk, and make the locked computer boot to it and then the password is removed. It is said that Kon-Boot is very, very easy to use and probably the fastest password reset. But some people who use it cannot make it work on Windows 7 PCs.
LCP: let's come to another tool that can reset Windows 7 administrator password free here. When using it to reset password, you should install it inside of Windows first. That is to say, you need an accessible user account on the locked computer. If you don't have one, then you will fail to use LCP to reset Windows password.
Anmosoft Windows Password Reset Ultimate: The reason why I list it here is not that it can get Windows 7 administrator password recovery free, but for that it is the best software among the four tools I list. Users also reset password through a password reset disk that is made by the software and blank CD/DVD or USB drive on another accessible computer. Although users cannot use Anmosoft Windows Password Reset Ultimate to reset administrator password with CD/DVD for free, they can set a new password easily. At the same time, users cannot use it to reset administrator password with bootable USB for free, but they can directly create a new admin account to replace the old one. All these features only belong to Anmosoft Windows Password Reset Ultimate. See the simple resetting procedure below:
1. Download and run the software on an accessible computer and insert a CD/DVD or USB drive (better to be blank) into the computer to burn a bootable disk.
2. Put the disk into the locked computer to reset forgotten admin password.
Just like I said at the beginning, if you are proactive enough to create Windows 7 admin password reset disk for free from Control Panel, you even have no need to consider any of them I listed above.
