New Windows And Linux Password Bypassing Method
By
CoderLab
It appears that removing Windows And Linux passwords on a machine where you lost the administrator password (or root password) has become my passion.
Now clearing pasword is not Good in some cases!! Guess Why! . There are various tools to clear windows accounts passwords
But here a new way of bypasswing windows and linux password is given.
This method allows to change contents of a linux kernel (and now Windows kernel also!!!) on the fly (while booting). :)
Kon-Boot is probably the fastest and easiest way to remove a Windows & Linux password. All you have to do is insert the Kon-Boot boot CD, and the tool does the rest for you.(a usb bootable method has also discussed at the end.)
Kon-Boot changes the contents of the Windows kernel on the fly while booting allowing you to log on without password. Thus the tool doesn’t change the SAM database. If you reboot again without using Kon-Boot you need the old passwords.I think, this would be the perfect password remove tool for all those desperate computer laymen who want to access their computer as quickly as possible without bothering their heads with terms such as system drive or SAM database.
In the current compilation state it allows to log into a linux system as 'root' user without typing the correct password or toelevate privileges from current user to root. For Windows systems it allows to enter any password protected profile without any knowledge of the password.
Entire Kon-Boot was written in pure x86 assembly, using old grandpa-geezer TASM 4.0.

Kon-Boot Windows&Linux | Download |
 |  Floppy image: CD ISO: |
Just boot the PC with Kon-Boot CD/Floppy, select your profile and put any password ,that’s all.The funny thing is Zipped version of Kon-boot for CD i.e ISO image is 8.5kb (110 kb after extracting ),where as Zipped version for floppy is 10kb which will goes to 1.4mb after unzipping it.
But every body Likes to Boot from Usb Pendrives.Since CDs are hard to put in your pocket, and many machines don't have floppies any more. What I needed was to be able to put Kon-Boot on
Thumbdrive.
So i have made a new Method to make Kon Boot Bootable from ThumbDrive..
But Actually This utility was not designed to work with USB sticks
I have already explained How to make usb drives bootable Using Unet Boot in
See My Article IN Live Usb SyStem
Steps To make Kon Boot Bootable
- Follow the directions in the article (Making Live Usb System)at http://coderlab.blogspot.com/2011/03/create-live-usb-systems-or-install.html using the floppy image and Unetbootin.
- Download the Following Filles in which changes had made to chain.c32 and syslinux.cfg Files
- Now extract that files to the root of the thumb drive
- Boot from the USB . F12 in most Dell Systems, F8 in Asus Motherboards,ESC in intel Sys.or Simble Go to Bios (Press DEL During Startup) and change the boot priority to "Boot from Usb".
- When the syslinux menu comes up, choose "1st Kon-Boot" first and step through it.
- The 2nd time the syslinux menu comes up, choose the option "2nd try boot from drive C: as hd1".
- 6. If hd1 does not work, try hd2 and so forth until you get in. If you have a a multi-boot system you may get a boot error, but it still worked for me.
7. On Linux login as kon-usr at the terminal (not GDM/KDM/XDM). On Windows use any valid local user name and a blank password (or even SASI, !!!!anything you type in as a password seems to work).
- Thats all ENJOY!!!!!!!!
