How to Reset a User Account Password in Vista
InformationIf you forgot the password for a user account, this will show you how to reset or change the password to gain access to the user account again.
Note- The password used in Vista is case sensitive. You might double check to make sure that you do not have the Caps Lock key on by mistake when typing it in.
- If you do not have a password for the user account, then clicking or pressing Enter with a blank field will usually work.
- METHOD THREE below should only be used a last resort to reset a Administrator account when it is the only account created, but it should do the job for you. Your only other option is to reinstall Vista.
- If you are using BitLocker Drive Encryption, then this will most likely not work.
- If all of these methods fail, then you will need to reinstall Vista.
TipFor a CMOS or BIOS Password:
You can usually reset this password by unplugging the computer and removing the battery on the motherboard for just a bit and/or temporarily crossing the CMOS jumper pin on the motherboard, then change or turn off the password in the BIOS at the next start. See your motherboard's documentation for these locations on it. You can usually find documentation at the motherboard's manufacturer's website.

WarningTo avoid not being able to log on, be sure to write down you user account's username and password and store it in a safe place for future reference if you need it. Another great option is to create a Password Reset Disk. See: See: How to Create a Password Reset Disk in Vista
METHOD ONE 
NoteThis is if you have a administrator account that you can logon with to change or reset the password for a Standard or another administrator account.
WarningIf you use an Administrator account to remove the password for any other user account, the user account with the removed password will lose access to its encrypted files, e‑mail messages that are encrypted, and stored passwords for websites or network resources. If the user account doesn't have any of these things, or the user doesn't mind losing them, then using an Administrator account to remove the password is a fast and easy way to recover from a forgotten password.
1. Logon to the Administrator account.
NOTE: If you forgot the Administrator account password, then logon to another Administrator account.
2. Reset or Change the forgotten password for the user account.
NOTE: For how, see: How to Remove a Password from a User Account in Vista
METHOD TWO NOTE: A password reset disk will allow you to reset the password for the user account it was created in. You had to of created one first though. See: How to Create a Password Reset Disk in Vista.
1. Start the computer up into the Logon Welcome Screen.
2. Click on the Click to Play button in the video below.
METHOD THREE NoteThis should only be used on a Administrator account that you forgot the password for and do not have another Administrator account (METHOD ONE or TWO) or a Password Reset Disk (METHOD FOUR) to use to reset the password. This should only be a last resort to gaining access to an administrative account.
TipDepending on what you use, you will need to have the CD/DVD or USB key drive listed first in the boot order in the BIOS settings to be able to "Press any key to boot from CD/DVD.".
