Design a Windows notification system that allows different applications to generate and display notifications. Focus on how prompts are framed and refined, and how AI-generated solutions are evaluated.

Design a Task Scheduler that can support one-time tasks and recurring tasks, with recurrence defined by cron expressions. **Approach**: Utilize ExecutorService, a Queue, and wait()/notify() for task coordination and execution. Consider how to apply the Strategy pattern so that different task types, especially those based on cron, can calculate their next execution independently.
