What Is Windows?
Windows is called an operating system.
An operating system is the main software that controls your computer.
Think of Windows as the organiser of your computer.
It helps your computer:
- Display information.
- Open programs.
- Save files.
- Connect to the internet.
- Manage printers and other devices.
Without Windows, using a computer would be much more difficult.
You don't need to remember the term "operating system".
Just remember that Windows is what makes your computer work the way it does.
The Windows Desktop
After you turn on your computer and sign in, you'll usually see the Desktop.
The Desktop is your main workspace.

Think of it like the top of a real desk.
You can keep useful items there so they are easy to find.
On the desktop you may see:
- Icons
- Shortcuts
- Files
- Folders
- A background picture
- The taskbar
Every computer looks slightly different because people often personalise their desktop.
Understanding the Taskbar
The taskbar is the long bar that usually appears across the bottom of the screen.

It gives you quick access to programs and important information.
The taskbar usually contains:
- Start button
- Search
- Pinned programs
- Open programs
- Wi-Fi status
- Volume control
- Battery level (laptops)
- Date and time
You will use the taskbar every time you use your computer.
The Start Menu
The Start menu is one of the most important parts of Windows.
To open it:

- Click the Start button.
- The Start menu appears.
From here you can:
- Find programs.
- Search for files.
- Open Settings.
- Restart your computer.
- Shut down your computer.
Whenever you are unsure where to begin, the Start menu is a good place to start.
Desktop Icons
Icons are small pictures that represent programs, folders or files.

Each icon gives you quick access to something on your computer.
Common desktop icons include:
- Recycle Bin
- Microsoft Edge
- This PC
- Documents
- Pictures
Some computers may have many icons.
Others may have only a few.
Understanding Windows (Application Windows)
When you open a program, it appears inside a window.
A window is simply a box on your screen that contains the program you are using.

For example:
- A web browser opens in a window.
- A document opens in a window.
- A photo opens in a window.
You can have several windows open at the same time.
Window Controls
Every window has three important buttons in the top-right corner.

Minimise
Hides the window but keeps the program running.
You can reopen it from the taskbar.
Maximise or Restore
Makes the window fill the screen.
Selecting it again returns the window to its previous size.
Close
Closes the current window.
If you haven't saved your work, Windows may ask if you want to save it first.
Notifications
Sometimes Windows displays small messages in the corner of the screen.
These are called notifications.

Notifications might tell you:
- An email has arrived.
- An update is available.
- A download has finished.
- Your battery is getting low.
You don't need to read every notification immediately.
Most will remain available until you have time to look at them.
The Mouse Pointer
As you learned in the previous guide, moving your mouse moves the pointer on the screen.
The pointer changes shape depending on what you're doing.

For example:
- Arrow
- Hand
- Typing cursor
- Busy spinning circle
These changes help you understand what Windows is doing.
Practice Activity
Spend a few minutes exploring your desktop.
Try to:
- Find the Start button.
- Open the Start menu.
- Find the taskbar.
- Look for the clock.
- Find one desktop icon.
- Open and close the Start menu several times.
There is no need to worry about making mistakes.
Simply becoming familiar with these areas is excellent practice.
Beginner Tips
As you become more familiar with Windows:
- Explore one feature at a time.
- Don't worry if your screen looks different from someone else's.
- Windows can be customised.
- Most mistakes can easily be undone.
- Confidence comes through regular practice.
