DigitalProductID is a binary value (use regedit to see what it looks like) and needs to be decoded. Try searching Google for some suggestions as to how to do it.

Some machines do not have a product key installed, such as volume Licensed machines (enterprise environments). In such cases the product key is stored as bbbbb-bbbbb-bbbbb-bbbbb-bbbbb. There's no problem with your code. You also mentioned that it works in some machines. Those machines must be retail versions of windows right??

Microsoft didn't mention it anywhere... it's just collection of unofficial things. Google for Produkey, it's a good product key checker... I found this description in their notes
