If you love the cool little utilities this one is for you. I actually came across this because some one shipped us a server with no password information and we didn't want to just reload the OS. The ability to at will reset the local admin password or any local account password is a great tool but packaged with all of these others really puts it over the top.

This is a fantastic utility to use.. I've used this more than I can remember when working on PCs.
