This information is encrypted so you will need help from a free utility called Belarc Advisor, which you can download here. Not only will this decrypt and show your Windows Product key, and those of any other MS products you might have, it reveals a vast amount of information about your computer's hardware and software, which it displays in a browser window. By the way, be aware that you are only allowed to install a copy of Windows on one computer at a time.
