Kon-Boot v1.0 Review

Skip your Windows password altogether with Kon-Boot

Kon-Boot is no longer available as a free download from the official website. See this list of free Windows password recovery tools for some free Kon-Boot alternatives.

The Kon-Boot password hacking tool has to be the easiest, and fastest, free Windows password recovery tool I've used. It's actually a password reset tool as many of these programs are, like ONTP&RE.

However, Kon-boot works in an entirely different way than those other Windows password reset/deleting tools so it's an excellent alternative if they haven't worked out for you.

Just download the free ISO file, burn it to a disc, boot from the disc, and you'll be back into Windows in a few minutes. Read on for more of my thoughts on this program, including a short how-to.

Kon-Boot Pros & Cons

While not my favorite password resetting tool, it does work:


  • Easiest password reset tool available
  • Software is freely available
  • ISO image is smallest of any free password recovery or reset tool
  • No access to Windows or knowledge of old password is needed
  • Works with 32-bit versions of Windows 7, Windows Vista, Windows XP, and some Windows Server OS's


  • Access to another PC required to burn ISO file
  • I could not get it to work from a USB drive
  • Not supported on newer or 64-bit Windows operating systems

More About Kon-Boot

  • Kon-Boot will temporarily remove the password on any 32-bit edition of Windows 7, Windows Vista, or Windows XP.
  • No installation is required—all password resetting is done from bootable disc or flash drive.
  • Kon-Boot is easy and fast, making the password reset task in Windows one of the most efficient I've seen.
  • ISO download is very small, a stark contrast to the huge download required for a true password recovery program like Ophcrack.

My Thoughts on Kon-Boot

Kon-Boot v1.0 is one of my favorite Windows password reset program, mainly because it's so fast and easy to use. I'd rank it higher among the other options available but it doesn't support 64-bit operating systems nor any edition of Windows 8 or Windows 101.

However, since it works so differently than Offline NT Password & Registry Editor, Kon-Boot is an excellent alternative if you need your Windows password reset and that free tool hasn't worked for some reason.

Kon-Boot requires a few post-cracking steps to be a real Windows password reset solution but nothing required by this amazing program is too difficult for anyone with the very serious problem of being locked out Windows.

How to Use Kon-Boot

To get started, visit the Kon-Boot download page. Once there, use the download button and save kon-boot1.1-free.zip somewhere on your computer. This ZIP file is extremely small so it shouldn't take more than a second or two.

Once downloaded, extract the files in Windows or with some other free zip/unzip tool. If prompted, the password is kon-boot. Once extracted, you'll see two folders. Locate the CD-konboot-v1.1-2in1.zip file and extract it, creating the CD-konboot-v1.1-2in1.iso file.

The file names make it look like you're using Kon-Boot v1.1 but it's actually v1.0, which you'll see noted when you run the program.

Burn this ISO file to a disc—a CD is fine. Burning an ISO file is different than burning a normal file so if you need help please see How to Burn an ISO File to a CD. Unfortunately, I was not able to get Kon-Boot working from a USB drive.

After creating the disc, boot from the disc by rebooting your PC with the disc still in the drive. Kon-Boot will start automatically. When you see the Kryptos Logic logo, hit any key. The rest of the process is automatic.

Once Windows starts, just log in to your account with a blank password. It's also possible that Windows will just log in automatically and skip the password asking process. Either way is fine.

Unlike other password reset tools, this isn't the end of the story. Kon-Boot has created a special situation where you can access your account but this goes away next time you start your computer. Unless you want to use Kon-Boot to login to Windows every time you start your computer, you'll need to change your password. Unfortunately, Windows will not let you do that from within your account right now.

To solve this problem, create an administrator account, log off, log on as the administrator, and then reset your account's password from the account you just created. Once you've done that, you can remove the disc, restart your computer, and login to your own account with the new password you created. Feel free to delete the administrator account you created to reset your password from.

Once this is all done, be sure to create a password reset disk so you can avoid using Kon-Boot ever again!

Having Problems Using Kon-Boot?

Did you have problems running Kon-Boot or did it not remove your Windows password? Try another free Windows password recovery tool or maybe even a premium Windows password recovery tool.

[1] Kon-Boot v1.0, the free version I've reviewed above, does not support 64-bit operating systems or Windows 8 or Windows 10. However, an updated and commercial version of Kon-Boot, available for $25 USD here, does support 64-bit versions of Windows, including Windows 8/8.1 and Windows 10. There are probably various other stability improvements as well. I have not personally tested this commercial version and do not recommend you purchase it unless you've exhausted your free password recovery options first.
