There are times when you may need to access a computer but you don’t know the password – this can include running an old machine you haven’t used it for years, using one purchased at a flea market or online auction, or even the need to quickly access your child’s computer for something. What ever the reason, accessing a computer without knowing the password is fairly simple with this free tool called Kon-Boot .
Of course there are alternatives like Ophcrack,However particularly I think Kon-Boot is the best tool, Which doesn’t ask any questions while gaining access to any PC without knowing its’ password.
Kon- boot is a software that will allow us to access any computer without knowing the password, and without modifying any files on Hard disk. All we have to do is to (just ) insert a boot (cd or floppy) disk Burned with Kon-boot software(110kb) in to any PC , and this offers unlimited access to that machine.
Kon-boot which was initially started as a small project for Linux (mainly Ubuntu),where 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. Now it was moved to windows platform where it enables Windows users to login to any password protected machine profile without any knowledge of the password.
This program works with the following versions of Windows: XP (SP1, SP2, SP3), Vista (Business, Ultimate), 2000, Server 2003 and 2008, and Windows 7. Kon-Boot also allows you to boot Linux (distributions: Ubuntu, Gentoo, Debian and Fedora) without a password as well.
Windows users doesn’t require any special instructions for using kon-boot , 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.
