Resetting profile password

Hi I recently purchased a Toshiba U305-S7467 with Windows Vista Home Premium. I bought this on ebay "slightly used". When I recieved it today it had a username of "Circuitcity" and it is password protected. Obviously it was a floor model... So the seller is going to send me a program to remove the password, but frankly I don't want to wait. Is there any software or any other way I can reset this? Every software I have seen cost money or seems to be for advanced users.

I should also mention it did not come with a recovery disk as I contacted Toshiba and they said I need one.

Any help would be great! Thank you
