Well one way is to store the install/first run date and license type (Trial or Full License), this can be done in either a text file or the registry, in either case it should be encrypted.

When your app starts it checks this value and compares it to the current date if more than 10 days have passed and it is a trial license you do not allow the program to run.

And no source code will be provided for this.
