1. The secret Start menu

Right-click in the lower-left corner to bring up a stripped-down Start menu

Moving your mouse cursor down to the bottom-left of the screen and left-clicking switches to the tiled Start page... but if you right-click instead, you'll be met with a menu linking to key areas of the operating system, including Control Panel, the command prompt and the Task Manager.

2. Sync your settings

Windows 8 supports the old user account system, but it can also create a new kind of user account that's linked to your Windows ID, and pulls in information from SkyDrive, Xbox, Hotmail/Outlook and all the other cloud services the company is pushing.

Sync settings, internet bookmarks and more across Windows 8 machines

A linked account can also sync your Windows settings (from your desktop wallpaper to your browsing history) across machines, which is handy if you have multiple computers at home or at work.

Launch the Settings charm, then choose 'Change PC settings' and open the 'Sync your settings' page to configure the feature.

3. Windows Defender

Windows Defender is back from extinction, taking over from Microsoft Security Essentials.

Windows 8 comes with Windows Defender, now with added antivirus capabilities

Unlike Security Essentials, Windows Defender tackles both viruses and spyware, and comes baked into the operating system.

You'll notice that it makes an appearance in Windows 8 if you don't already have antivirus and anti-spyware tools in place, leaping into action to plug whichever security gaps need filling.

4. Simpler shutdown

It's the same keyboard shortcut as in previous versions of Windows, but it's worth mentioning here because Windows 8 makes shutting down your PC more drawn out.

Use the traditional Alt+F4 shortcut as a quicker way to power down your PC

Rather than opening the Charms bar, clicking Settings, selecting the Power button and choosing 'Shut down', simply press Alt+F4 while viewing the desktop.

You can then press Enter to shut down the PC or choose an alternative option from the drop-down menu.

5. Built-in screenshots

Windows 8 will automatically save screen grabs whenever Win+PrtScn is pressed

Windows 7 had the Snipping Tool for taking screenshots, and this tool is still around in Windows 8.

However, there's an even easier way to capture what's happening on your display — press the Windows key and the PrtScn button together, and a PNG grab will be automatically saved to your Pictures library.

6. Keyboard shortcuts

Use the Ctrl+Tab shortcut to see all of your Windows 8 apps listed together

Swiping and tapping around Windows 8 is fine on a touchscreen interface, but what about standard laptops and desktops?

Knowing the keyboard shortcuts for Windows 8 can save you a lot of clicking and dragging with the mouse, and make it easier to navigate the operating system.

Win+C brings up the Charms bar, for example, while pressing the Windows key on its own switches between the desktop and the Start page.

Another useful one: hit Ctrl+Tab on the Start page to switch to the 'All apps' view.

7. Snap your apps

As you may already know, Windows 7 allowed you to snap windows to the side of the screen by clicking and dragging the title bar.

Windows 8 goes one step further, enabling users to dock a Start page app (like Weather or Bing) to the side while you work on the desktop.
