Now any user can logon to windows or linux system with Administrator or Root privilege, no matter what kind of permission he/she have by simply using a bootable floppy or bootable CD. And it is possible by using Kon-Boot.
Kon-Boot is a prototype piece of software which allows to change contents of a linux kernel (and now Windows kernel also!!!) on the fly (while booting). In the current compilation state it allows to log into a linux system as ‘root‘ user without typing the correct password or to elevate privileges from current user to root. For Windows systems it allows to enter any password protected profile without any knowledge of the password.
Kon-Boot for Windows enables logging in to any password protected machine profile without without any knowledge of the password. This tool changes the contents of Windows kernel while booting, everything is done virtually – without any interferences with physical system changes. So far following systems were tested to work correctly with Kon-Boot (however it’s quite possible other versions of listed Windows systems may be suitable as well):
| Tested Windows versions |
| Windows Server 2008 Standard SP2 (v.275) |
| Windows Vista Business SP0 |
| Windows Vista Ultimate SP1 |
| Windows Vista Ultimate SP0 |
| Windows Server 2003 Enterprise |
| Windows XP |
| Windows XP SP1 |
| Windows XP SP2 |
| Windows XP SP3 |
| Windows 7 |
Current Kon-Boot release was tested with following Linux distributions:
Kernel | Grub |
Gentoo 2.6.24-gentoo-r5 | GRUB 0.97 |
Ubuntu 2.6.24.3-debug | GRUB 0.97 |
Debian 2.6.18-6-6861 | GRUB 0.97 |
Fedora 2.6.25.9-76.fc9.i6862 | GRUB 0.97 |
Notes:
1 – setreuid method example not working
2 – logging without a password not working (maybe because this SELinux issues?)

the interface of Windows 7 is great but in my opinion Windows XP is still a very solid and stable operating system. Right now, I would never give up XP for Windows 7.
Windows 7 is much better than Windows Vista when it comes to performance. i like Windows 7 just like Windows XP
i just installed Windows 7 on my PC. i just hope that it is as stable as Windows XP.
There seem to be alot of these password/login bypassing boot disks surfacing, there great but rely on local access to the machine. I work as a network penetration tester and we use the NetApi exploit to hack alot of remote windows XP/Server 2003 machines during jobs.
I have discussed it in my article “Remote windows hacking with the netapi exploit” you may find it interesting.
Great blog, keep up the good work

Actually I lost my Windows 7 password and hope to remove it, so that I can login without password. Finally I use SmartKey Windows Password Recovery to remove the password. Then I can login Windows 7 without typing the password. You can Google Search “login windows 7 without password smartkey” to know more about it. By the way, what do you think of it?
