If you reboot again without using Kon-Boot you need the old passwords. Thus the tool doesn't change the SAM database. Update (see comment below): Kon-Boot changes the contents of the Windows kernel on the fly while booting allowing you to log on without password. Kon-Boot just reboots Windows and sets an empty password for all accounts it finds, enabling you to log on to any of the local accounts without a password. You don't receive a message that informs you whether the mission has been accomplished. The last part is very quick and only takes a fraction of the time that the tool needs to display its hello-world screens. You have to wait here until the ego screen finishes its display, and then Kon-Boot will finally do what it is supposed to do. Somehow this destroys the beauty of this tool because it would certainly be even cooler to hack Windows without touching a key.Īfter you press a key, a second 'I-am-so-proud-to-be-hacker-screen' appears. At this point, you have to press a key for Kon-Boot to continue.

Shortly after the CD drive starts spinning, you will see the Kon-Boot welcome screen.
