Kon-Boot is software which allows you to bypass a Windows or Linux password by temporarily modifying the kernel. This is great for those times when you are working on a client’s pc but forgot to ask for the password. Kon-Boot is one of the simplest programs I have ever used, and it works very well. Simply burn the iso and boot into Kon-Boot. It will automatically load and then start the Windows boot process. When you get to the login screen click on any user and hit enter and you will log into the desktop, no matter how strong of a password was used.
The process does not change, modify, or delete the user password, it simply bypasses it by temporarily modifying the kernel. When you are done take out the cd and reboot or shutdown. The user login will again require a password and won’t log in unless it’s provided. It’s that simple.
Kon-Boot is free for personal use on the original developer’s website, but the version is no longer being maintained. Maintained personal use licenses and commercial use licenses can be purchased from Kryptoslogic.
