If you have forgotten your password, if you have another user account with
administrative privileges you can log into that account and change your
original user account's password from the User Accounts applet in Control
Panel. If you don't have another account like this set up or don't have the
password to it, you'll need to log into the built-in Administrator account.
In XP Home, boot the computer into Safe Mode. Do this by repeatedly tapping
the F8 key as the computer is starting up. This will get you to the right
menu. Navigate using your Up arrow key; the mouse will not work here. Once
in Safe Mode, you will see the normally hidden Administrator account. The
default password is a blank.

In XP Pro, you do not need to go into Safe Mode. At the Welcome Screen, do
Ctrl-Alt-Del twice to get the classic Windows logon box. Type in
"Administrator" and whatever password you assigned when you set up Windows.

To change the built-in Administrator account in XP Pro if you can log into
another account with administrative privileges reset the password in the
Local Users and Groups snap-in in Microsoft Management Console (MMC):

1. Click Start, and then click Run.
2. In the Open box, type "mmc" (without the quotation marks), and then click
OK to start MMC.
3. Start the Local Users and Groups snap-in.
4. Under Console Root, expand "Local Users and Groups", and then click
Users.
5. In the right pane, right-click Administrator, and then click Set
Password.
6. Click Proceed in the message box that appears.
7. Type and confirm the new password in the appropriate boxes, and then
click OK.

If you reset the built-in Administrator account's password in Home or have
Pro and don't remember the password, use NTpasswd to change the built-in
Administrator account's password to a blank.

This is simple if you download the SmartKey Windows Password Recovery software make it bootable cd or dvd . And start the booting from this cd and flow the insrrctions on screen you will go to password recovery option and set all the password for administrator and if you get admin pass you can change all use passwords.
