It Plays as Hard as it Works

Multitasking Made Easy

It’s easy to do more at once. Snap multiple apps side by side in a single view for easy multitasking.

The Start Screen

Personalize your Start screen with your favourite news, friends, social networks, and apps. Customisable colours and backgrounds and four different sizes of tiles make your device as unique as you are.

Mouse, Keyboard—and now Touch

Windows 8.1 works harmoniously with various types of devices, including touch, mouse-and-keyboard, or both. Whatever kind of device you have, you'll discover fast and fluid ways to switch between apps, move things around, and go smoothly from one place to another.

The Apps you Want

In addition to great built-in apps for email, people, photos and video editing – you can also download thousands of popular apps from the Windows Store.

Your files, Everywhere

Stay connected to your photos and important files and access them on your phone, tablet or PC with SkyDrive. By signing in with your Microsoft account to any of your PCs running Windows 8.1 and you'll immediately see your own background, display preferences, and settings.


Stay up to date and more secure with Windows Defender, Windows Firewall, and Windows Update.

You Keep all your Files

If your PC is running Windows 7, your files, apps and settings will easily transfer to Windows 8.1 Pro.


Windows 8.1 starts up faster, switches between apps faster, and uses power more efficiently than previous versions of Windows, including Windows 7.

You Keep Familiar Programs

Programs that run on Windows 7 will run on Windows 8.1 Pro.

Your Familiar Desktop

From the Start screen, you are just a click away from the familiar Windows desktop you know so you can do the stuff you’ve always done.

Your Office. Your Way.
