try searching the web for third party software that offers to recover lost password in xp..there's no easy way to recover lost password..or try using other log in name such as Power Users.. Backup Operators..maybe the account is turned on...

If you didn't set administrator password , press ctrl+alt+del on welcome screen then type administrator in user name filed and press enter.
but if you set admin password, use bootable disk to remove your password.

Easy way:


as soon as the pc switches on tap F8 repeatedly. A menu will come up - choose "Safe Mode" and then wait a while. Lots of text will come down the screen and the graphics will look crappy but dont worry. There will be a user called "Administrator" shown on the welcome screen in this mode. Log in as it (no password) and then delete the password on your usual user account

As jb posted above, if the Administrator ac has no password, then you are in..
I do hope you have permission to be using that computer. Do not know the username?!

Yes I do have permission. Its my boss laptop and he has asked me to fix it for him.
What if the administrator username was changed

not likely

Or, to expand a little on sittas's post... the Administratot remains the Administrator - this is the base admin account; I don't think it is possible to change the name from Administrator. Other admin acs are initially clones of this one.

Most motherboards manufactured over the last decade or more use a battery to sustain the dynamic Bios/CMOS settings for the motherboards PROM chip. These dynamic settings are those manually set by either the computers manufacturer or you, the user. There are two ways to erase these dynamic settings, by either resetting a jumper on the motherboard itself (referred to as a "clear CMOS" jumper), or by physically remove the power from the computer (disconnecting the power plug) and then removing a battery (used to maintain power to the PROM chip that contains the Bios/CMOS information) from the motherboard.

Listen to the previous posts telling your to check the Administrator account. It's often left open. If you cannot get in that way you have to hack in.

Irresponsible persons should stop reading here.

I use OPHcrack. It's a free tool and usually gives up Windows XP passwords in about 15 to 30 min depending on the speed of the PC. You can find OPHcrack here. Download the livecd and burn to disk, it has a bootable version on Linux on it. The website has good documentation on how to use the tool and there are even instruction videos available if you do a quick search. If you need help with the tool, post back here.

I don't have access to modify my own posts. The moderator will have to remove the information if it's inappropriate.

OPHCrack is known... but I thought it had problems with passwords over a certain length.. 12 charactrers or so? And you need a fast processor.. and a lot of RAM to get it to do it before you die. For a fast job the rainbow table download is um... big. Huge.

I have not used OPHCrack, sittas, cos I don't forget passwords but I know the pgm is based on rainbow tables, and you do it slowly with a small table and small RAM, or more quickly with a large table and large RAM. Now you can generate those tables... or dl them. I reckon that a 1/2GB dl is huge. A 1 1/2GB table is monstrous. But I don't dl movies, so...
Check out this site and play if interested. Sourceforge has a selection of rainbow tables also.
