How about:

at startup, check if the first start time is stored somewhere in the registry (you chose a registry path of your own)
- if yes, calculate the elapsed time since that date
     if expired --> exit
     if not expired --> continue
- if no, set the current time in some registry variable --> continue

Regards
Andi

PS: this is the basics. You may chose to store the date somewhere else and/or to calculate some hash with the first date to make it harder to cheat...
PPS: We do not do your coding here. If you have a more specific problem we are glad to help you :-)

What have you tried? Even as a beginner you start somewhere. Are you attending a course or a training? If yes, check your text book on how to start. If you learn it yourself, work through a basic tutorial and chose adequate training examples.
If you then have questions, go ahead and ask *specific* questions on a *specific* problem. You don't get any one here to do your job. If you are a beginner, you probably want to learn something. If we past the solution here for you, you have no benefit in learning it.

PS: You may have noticed that people here try to write full sentences with full words - "u" and "plz" and alike are crap.
