How to find the product key of Windows or office installed on your computer?

When you have paid a lot of money for software and find later on down the track that you have lost the product key, don’t panic yet. The product key will be stored on your computer and can be retrieved manually, which is a nightmare, or with the help of a free program. I am presuming that in the past you purchased a genuine copy of either Windows or Office but have lost the product key. Hopefully you still have the programs CD. If you do not have the original CD this will not help you.

Isn’t it illegal to find a product key for a program?

It is illegal to find a product key on the internet and use this, however if you have previously installed a genuine paid for copy of either Microsoft Windows of Office 2003 or 2007, then it is ok. It is understandable and most likely that people now days loose their product keys. At the time of buying a new computer or installing a new program, they do not realize how important that product key is. As long as you still have the original CD, then you can find the product key stored on your computer.
