Applies to: Microsoft Windows NT, Windows 2000, Windows XP

Recover lost user password

If you have lost and forgotten the password of a user of the Windows computer, but can still log in to the system under another user, there are several ways you can regain access to the account.

Solution

Check the boot drives

• Check that there are no removable drives connected to the computer which it might be trying to boot from, including floppy disks and CDs / DVDs.
• Go into the BIOS Setup utility and check that the hard disk settings are correct and that the first drive in the boot order is the hard disk.

If this does not resolve the issue then you will need to try repairing the hard disk boot sector. If you are using Windows 95/98/Me and have made a recovery disk then you can use this. If you have original Windows 2000 or Windows XP installation media then you can boot from this and use the Recovery Console to perform a repair from the command line.

If you don't have a bootable repair disk then the easiest way to fix this problem is to use Spotmau PowerSuite.

• Insert the Spotmau PowerSuite CD and start the computer. The main menu will appear.

• Click 1. Hard Disk Tools.

• Click 1. Partition Genius.

• Click 1. Partition Genius.

• When Partition Genius starts, click Tools, Repair MBR.

• You should see the message "Repair Master Boot Record (MBR) OK!" Click the X button to close Partition Genius, then restart the computer.

Using the Windows Recovery Console

If you have a Windows 2000 or Windows XP installation CD from Microsoft you may use the Recovery Console to run tools to repair the boot records.

• Insert the Windows CD and start the computer.
• When the Welcome to Setup screen appears, press R.
• Select the Windows installation you wish to repair (usually number 1) and press Enter.
• When prompted, type the administrator password and press Enter.
• If the primary hard disk partition is a FAT partition, type the command:
  FIXBOOT
  and press Enter.
• Type the command:
  FIXMBR
  and press Enter.
• Remove the Windows XP CD from the drive and restart the computer.

If this does not resolve the problem:

• Insert the Windows CD and start the computer.
• When the Welcome to Setup screen appears, press Enter to set up Windows XP.
• Press F8 to accept the license agreement.
• Select the Windows installation you wish to repair and press Enter.

A repair installation of Windows will be performed.
