“Have you ever wondered what makes your computer work the way it does?
Let’s start with a simple question

What operating system does your computer use?
Windows is an operating system that controls how your computer works. It helps you open apps, manage files, and connect to the internet. Most people use it without even realizing how much behind the scenes.
Windows is a program developed by Microsoft that helps run your computer. It controls everything, but it also makes it easy for you to do what you want.
Here’s what Windows does:
- It controls the hardware (things like the mouse, keyboard, and screen).
- It manages the software (apps like Microsoft Excel or Brave Browser).
- It gives you a friendly screen with buttons and icons, so you don’t need to type commands.
So, when you click the Start button or open a folder, you’re using Windows to do that.
