free at http://www.gtopala.com/ has the ability to read stored and sometimes misplaced usernames and passwords by looking at the Software>Secrets folder.
Additionally it can display passwords that appear "*****" (or other obscuring characters, like bullets) by running the Tools>Eureka! feature.
Very handy, and nothing has to be installed. It is a standalone executable.
Oh, by the way, NO it does not tell you passwords for other users, unless you log on as them and then run SIW as that person.
How do I access the log created by Windows Auto Complete so that I can retrieve a forgotten password that no longer pops up automatically?
