Using a Recovery Disc on Vista

Find a Windows Vista installation or recovery disc. In order to perform this method, you will need to enter the Recovery Console, which can only be accessed with a Windows Vista installation or recovery disc.
1. You can download a Windows Vista ISO file and burn it to a DVD.
2. The installation disc doesn't need to be the one you use to install your operating system, but it does need to be for the same version of Windows.
Insert the installation disc into your computer. The disc must go label-side-up in your computer's CD tray.
Restart your computer. Click the upward-facing arrow next to the

Power icon, then click Restart in the pop-up menu.
Press your computer's BIOS key. As soon as your computer begins restarting, start pressing the BIOS key. This key will be listed at the bottom of the screen.

Select the "Boot" tab. Use the arrow keys to move over to the "Boot" or "Startup" tab.
1. Skip this step if you don't see a Boot tab.
Change the boot order. Select the Disc, Disc Drive, or similar option, then press the + key until the selected option is at the top.
Save your settings and exit the BIOS. There's usually a key that you can press to do so; look for the "Save and Exit" key on the right side of the screen.

Press any key when prompted. Doing so will launch the Windows Recovery window.

Enter the final command. Type in y and press ↵ Enter. This will indicate a "Yes" response, which enables Command Prompt on the Windows login screen.
Remove the installation or recovery disc, then reboot your computer. Once the computer finishes rebooting, you should be back at the login screen.
Click the "Accessibility" button. It's the blue, dial-shaped option in the bottom-left or bottom-right corner of the screen. Doing so will open the Command Prompt app.
Enter the password reset command. Type in net user username new_password, where "username" is the username for the account whose password you forgot and "new_password" is the new password that you want to assign.
1. For example: to change the password to "ilikelemons" for an account named "citruslover", you would enter net user citruslover ilikelemons here.
Press ↵ Enter. This will immediately change the password for the selected account.
Log in with your new password. Select your user account and enter the new password that you just set. You should be able to access the account now.
