6. 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.

10 hidden features in Windows 8
Many Windows 8 apps have a mini mode for displaying them at the side of the screen

So, for example, you could keep an eye on the forecast while playing around in Photoshop, or stay in touch with your Twitter feed via the People app while crunching numbers in Excel.
To dock a full-screen Start page app, drag it from the top to the left or right of the screen. You can run Start page apps alongside each other too.

7. Reinstall windows

Here's a feature you might not come across until something goes wrong - Windows' new reinstall routine, known as Reset (on the PC Settings page).
There's no need to dig out discs or serial codes, because everything you need is already available, hidden away on the hard drive.

Returning Windows to its factory setting takes a handful of clicks, and has never been easier.

Alternatively, you can do a 'refresh', which brings back all the default operating system settings, keeping your personal files, settings, the programs that came with your PC and any applications that you have downloaded from the Windows Store.
