What should your do when you forgot the password to login to windows system? Ask an administrator to reset the log on password for you. If you yourself are administrator, and you can't remember the administrator password, the problem get a little tricky, and probably hard to recover the "forgotten password" again. Before you search for recovery CD or Windows DVD to format and reinstall Windows onto the computer, here a few solutions you can try to unlock the windows to gain access to the system again, at least by resetting the password
Method 1: Take a rest, and try hard to remember the forgotten password
Sometimes, human being is a little weird. You won’t get the thing that you urgently need. So have a coffee, take a snap or even come back after a few days, you may found that you suddenly ‘remember’ your Windows password.
Method 2: Try No Password Administrator Login Backdoor
In Windows XP (not Windows Vista as Administrator account is not enabled by default), there is built-in Administrator user account, that has administrative credentials, enabled by default, and without any password to protect the account from been access. If you didn’t change this Administrator’s password, then try to sign in to Windows XP without password.
Method 3: Reset password from another user account with administrator credentials
If you cannot log on to Windows by using a particular user account, but you can log on to another account that has administrative credentials, follow these steps on how to do the trick: Log on to Windows by using an administrator account that has a password that you remember. You may need to start WinXP in safe mode. Click Start, and then click Run. In the Open box, type “control userpasswords2″, and then click OK. Click the user account that you forgot the password for, and then click Reset Password. Type a new password in both the New password and the Confirm new password boxes, and then click OK.
Method 4: Do-It-Yourself (DIY) third party recovery tool
There are a lot of tools and utilities that can be downloaded and used to recover, reset, retrieve or reveal existing password. Take Windows Password Unlcoker （passwordunlocker.com）for example, Windows Password Unlcoker creates a password reset CD that work during the boot process and instantly reset Administrator or other account passwords and Windows security setting which prevent you from logging in.

provides a tool to recover lost Windows XP passwords. It works for administrator and user accounts, it doesn't change the password just tells you the old one. It works with encrypted files (EFS) and password hashes. It even works if no passwords at all are known for the machine (as long as you have another computer with internet access to view this website with). Author claims it also works with Windows NT and Windows Server 2003 and Windows Longhorn, but the BEST thing about it is the fact that it won't reset your passwords, but simply reveal them for you to remember and then use. Give it a try. The author would like to receive feedback. The fee for the service is very cheap, and is really just to cover server costs. Note: You'll need a blank floppy to run the process.

Update: Author now offers the same tool as a CD image for those of you who do not have a floppy in their computer. Usage, instructions and additional information can be found
