We will use a small software to get passwords from messengers installed in a computer. These passwords are usually encrypted but this software will decrypt them and will show you in the form of normal text. You can also execute this in another computer to get the passwords. You can also make an autorun usb drive to acquire passwords from this software and also from browser. But for browser you have to use other application. I will post this trick later. Now just stick to this software. Its name is Messen Pass.

MessenPass is a password recovery tool that reveals the passwords of the following instant messenger applications:
MSN Messenger
Windows Messenger (In Windows XP)
Windows Live Messenger (In Windows XP/Vista/7)
Yahoo Messenger (Versions 5.x and 6.x)

Note: MessenPass can only be used to recover the passwords for the current logged-on user on your local computer, and it only works if you chose the remember your password in one of the above programs.Also some antivirus might consider this as virus but not in most cases.
