You can click here to download and extract the windows password recovery program file, then burn the extracted .ISO file as an image to a blank CD (use the Imgburn burning program if needed). Then you can boot the CD disk from the CD/DVD drive and follow the steps to reset the windows password; you can click here for more details.
But it can be complicated; it's easier resetting the computer to factory settings: turn off the toshiba laptop, then press & keep holding the key 0 (zero) and turn on the laptop until a system recovery menu appears.
If that does not work, do you have the windows 7 / recovery disk? Thank you.
