Windows service

A Windows Service is like a robot that lives in your computer and does things automatically for you. This robot is created by a person who writes a program in a special way so that it can run in the background without bothering you while you use your computer.

Let's say your computer needs to periodically check the weather forecast and remind you if there's a chance of rain. With a Windows Service, you could program a robot to check the weather every hour and send you a message if there's rain in the forecast. This robot would run in the background and you wouldn't even know it's there unless it tells you about the rain.

Another example could be a robot that automatically backs up your files every day while you're not using your computer. You might not even know it's working, but it's there to protect your important files.

Overall, a Windows Service is kind of like having a personal assistant that you don't have to supervise, but can trust to do important tasks for you automatically.
