Microsoft has a product called Software License & Protection Services (SLP Services) to help ISVs protect and manage their software from piracy. This same technology may be used to manage trials as well as conversion from trial to a licensed product via a different license key. You can take a look at http://www.microsoft.com/slps.[^]
These links will help you understand how you can solve this Licensing issue. Here are the links;
