I lost my toshiba window 7 product key number. how can i get it again please?

Hello,

You can retrieve your Windows product key by downloading a small (approx. 1MB), yet very useful freeware called Keyfinder.

Once downloaded, just install (you can bypass the registry tool installation) it and launch the program and there you will get your Windows product key.

Download link : Magical Jelly Bean Keyfinder

Hope this helps!!

Well, I´m not sure which product key you´re looking for but this website (http://www.product-key.com/) helps you find it.
