推荐答案

如何关于：

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

PS：这是基础知识。您可以选择将日期存储在其他地方和/或计算第一个日期的一些哈希，以使其更难作弊...

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...
