I have just finished up a small windows application in c#.

I have created a setup and now I want to run this application only for 7 days.
(after that it should be registered with any serial keys, or any other method).

How can I achieve this?

Another option is a timer control, run from initial set up, and after 7 days it asks for a key.
Base the algorithm of the key on a date control and then email it after payment/registration is received.

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
