I re-installed my Windows 7 installation and I am being asked for the Product Key. But alas, stupid me, I had jotted down the Product ID and not the actual Product Key. Unfortunately, I lost the Windows case where the key is at, so I am wondering if there is a way to retrieve the product key just by using the Product ID?

The product key is stored in the registry, and you can retrieve it from there with tools like KeyFinder. Beware that if you bought the system pre-installed, the distributor most likely used their product key for the initial setup, which won't work with your installation media.
