Do some coding for checking whether it reached 10 days after installation or not (on application start). If it reached the limit(10 days), prevent the application from opening or running. If not, the user continue using the software.
You can accomplish this with your own coding techniques, or try the open source project : ActiveLock

This little program will allow the user to try software upto 10 days, however you can modify the trial days in the regmodule,
