If I forgot the administrator’s password

How can I gain access to a Windows NT/2000/XP/2003 computer if I forgot the administrator’s password? How can I reset the administrator’s password if I forgot it?

Ok, so you say you forgot your Windows administrator’s password, huh? Oh well, it doesn’t really matter if you did or you just say you did. The fact is that you need to gain access to a computer and you cannot «remember» the administrator’s password.

How can you get out of this situation without formatting and re-installing the operating system?

One method of gaining access to the system is by trying hard to remember the forgotten password, or a password of another user which has the same level of administrative rights. However I don’t think this approach will help you, otherwise you wouldn’t be sitting here reading article, would you?)

Another method is by trying to restore a backed up System State (in Windows 2000/XP/2003) or a ERD (in NT 4.0) in which you do remember the password. The problem with doing so is that you’ll probably lose all of the recently add users and groups, and all the changed passwords for all of your users since the last backup was made.

A third method might be to install a parallel operating system on a different partition on the same computer, then use a simple trick to gain access to the old system. Read more about it on my Forgot the Administrator’s Password? – Alternate Logon Trick article.

The fourth option is by using 3rd party tools that will enable you to reset the lost password and logon with a blank password.

Freeware Password Recovery Tool

Free Windows password-cracking tools are usually Linux boot disks that have NT file system (NTFS) drivers and software that will read the registry and rewrite the password hashes for any account including the Administrators. This process requires physical access to the console and an available floppy drive but it works like a charm! I’ve done it myself several times with no glitch or problem whatsoever.

Beware!!! Resetting a user’s or administrator’s password on some systems (like Windows XP) might cause data loss, especially EFS-encrypted files and saved passwords from within Internet Explorer. To protect yourself against EFS-encrypted files loss you should always export your Private and Public key, along with the keys for the Recovery Agent user. Please read more about EFS on my What’s EFS? page. Out of the following list, the only tool that will no cause any harm to EFS-encrypted files on your hard disk is the Windows Password recovery system.

EBCD – Emergency Boot CD – Bootable CD, intended for system recovery in the case of software or hardware faults.

(v0.61 – October 2004)

EBCD is a bootable CD, intended for system recovery in the case of software or hardware faults. It is able to create backup copies of normally working system and restore system to saved state. It contains the best system software ever created, properly compiled and configured for the maximum efficient use.

EBCD will be very useful when you need to:

  • Copy/move files (with long names, not necessary in CP437 encoding) from/to the disk but OS which can handle them (windows, Linux…) cannot boot. In particular, you may create a backup copy of normally installed and configured Windows and later restore Windows from such backup copy. So, in the case of fault OS itself and all software and its settings can be restored in 5-10 minutes.
  • Perform emergency boot of Windows NT / 2000 / XP. When the loader of this OS on the hard disk is damaged or misconfigured, you are able to load OS using another, standalone loader from this CD.
  • Recover master boot record of HDD. This allows to boot OS after incorrect uninstallation of custom loader (LILO, for example), which made all OS on your PC not bootable.
  • Delete, move, copy to file (image) and re-create partition from file. Image transfer over network is also supported: so you may configure one PC and then make contents of hard disks of other PCs same as contents of the hard disk of the first one.
  • Change password of any user, including administrator of Windows NT/2000/XP OS. You do not need to know the old password.
  • Recover deleted file, even file re-deleted from Windows Recycle Bin, and, in contrast, wipe single file or a whole disk so that it will be impossible to recover it in any way.
  • Recover data from accidentally formatted disk. Sometimes it helps to recover data from the disk, damaged by a virus.
  • Recover data from a floppy disk, which is not readable by OS. Format 3.5″ disk for 1.7 Mb size.

Also the disk includes full set of external DOS commands, console versions of the most popular archivers/compressors.

Moreover, emergency boot CD includes minimal Linux distribution (Rescue Linux distribution) which may be very useful to a professional user.
