Windows XP Passwords Rendered Useless
By Brett Glass, ExtremeTech 

Windows guru Brian Livingston reports that inserting a Windows 2000 CD into an XP system allows one to bypass all password protection and manipulate any part of the machine at will. "Anyone with a Windows 2000 CD can boot up a Windows XP box and start the Windows 2000 Recovery Console," says Livingston. The intruder has Administrator privileges even if he or she does not provide a password, and can also assume the identity of any other user of the machine.   

"I notified four Microsoft executives of the XP flaw weeks ago, but haven't yet received an official response," writes Livingston. "There's no Knowledge Base article about it, and there may not even be a good solution to the problem."

While one does need physical access to the machine to exploit the flaw, this will be little comfort to the administrators of academic computer laboratories and other facilities where users can easily pop a CD-ROM into a computer.

hia again, i have had a few ideas of how to remove the password.

1. You could do the bypass process using the win XP CD and repair the installation by selecting the process from the menu that will replace the critical system files thus fixing any problems you have with any system files. (it replaces things like "logonui.exe" which is the logon screen in XP). This might work but i haven't done it before so i don't know wether it gets rid of the passwords too. 

2.  You can probably do it if he has a FAT hard drive and not an NTFS by going to this site and downloading a bootdisk or sumthink that shud allow you do it. http://home.eunet.no/~pnordahl/ntpasswd/. Make sure you read the whole site first otherwise you cud screw ur system up.

3. if all else fails then you can backup the files you need on ur pc using the commands for the recovery console below. And then just do a simple re-format.

Good Luck
