Insert Window Vista installation disk to the CD-ROM drive, restart your computer. Do the settings under CMOS to boot the computer through CD. When the installation interface appears, click "Repair Your Computer" (repair system) in the subsequent pop-up dialog box, select the "Command Prompt". After the system calls the command prompt window, enter "mmc.exe" and press “Enter”, then the console will be called. Select the file "Add / Remove Administrative Unit", the system will pop up another dialog window once again. In the left side of the dialog window select "Local Users and Groups", and then click "Add". At this point, the system will add "Local Users and Groups" to "Console Node". Click "OK" to complete the adding process. After adding is completed, the system returns to the console interface, click "Local Users and Groups" on the left side of the window, then click "User” and the system will list all the users in the right side of the current window. Right-click the user you are to crack, select "Set Password" in the pop-up "Set Password for Users" dialog box, and click "Continue”. The system pops up a window for you to set a new password. At this point, the Vista system does not require you to enter the previous password, but to set a new password directly. After you enter a new password, click “OK”, and the system will pop up a dialog box, indicating the setting is successful.

You can try to reset the password in Vista with command prompt.
1. Press F8 to enter Advanced Boot Options just before the Windows loading screen appears.
2. Choose Safe Mode with Command Prompt.
3. Log in with an administrator account when you can see the log on screen.
4. Type net user in the command prompt and then hit Enter. All the Windows account user names will be listed for you.
5. Type net user Helen 123 and hit Enter.
‘Helen’ is your locked Windows account user name. And ‘123’ is the new password you want to reset for the account.
