Also I'm on Vista and now I can't log-in to my normal user account. It keeps telling me the password is wrong when It's not. It actually logged me in for about two minutes and then shut down saying the password was incorrect.
If you have lost or forgotten your password for logging in to a computer running the Windows Vista operating system, there are a few different options:
If you created a password reset disk for Windows Vista, you can use that disk to reset the password on your account. For more information on how to create and use password reset disks go to the Microsoft Knowledge Base:How to create and use a password reset disk in Windows Vista
If you don't have a password reset disk, the other option is to log on as the Administrator (or to have the person who is the machine's Administrator log on) and change the password for your user account.
If you don't know the Administrator password, and don't have a password reset disk, then you will not be able to log on to Windows Vista, and will need to reinstall the operating system and recreate any user accounts.
