Problem:

MSN Messenger Service allows users to save their e-mail password using the

"Save this password so I don't have to enter it every time i log on" checkbox when try to logon in the Messenger Service.

The e-mail and the password are stored in the registry key KEY_CURRENT_USER\Identities\9C53B920-A2E8-11D1-A59D-008048B12C6E\Software\Microsoft\MessengerService\

PasswordMSN Messenger Service

{9C53B920-A2E8-11D1-A59D-008048B12C6E} = this change in all machines

This information can be decrypted using the MessengerServiceEmailPasswordDumper 1.0

Solution:

If a user does not click the 'Save this password so I don't have to enter it every time i log on' checkbox prevents the password from being stored and decrypted.
