If you forget your Windows password, you can use a password reset disk to create a new one. We recommend that you create a password reset disk when you create your password, so you don't lose access to your files and information.
A password reset disk can only be created for local user accounts. If your computer is on a domain, a system administrator can reset your domain password.
To complete these steps, you'll need removable media (a USB flash drive or floppy disk).
Insert your removable media.
In the left pane, click Create a password reset disk, and then follow the instructions. Make sure you store the password reset disk in a safe place.
