It Plays as Hard as it Works

Windows 8.1 gives you the power to quickly browse, watch movies, play games, polish your resume, and pull together a killer presentation — all on a single PC. Now you can organise up to three apps on your screen at once in a single view.

The Start Screen

Personalise 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.

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.


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


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

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.

Multitasking Made Easy

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

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.

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.

You Keep all your Files

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

You Keep Familiar Programs

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

Your Office. Your Way.

Experience Office at its best on Windows 8 devices. Discover new and better ways to create, edit, and browse—using a keyboard, pen, or touchscreen. Don't forget: Office is not part of Windows 8.

Some features require Windows 8.1. Update available through Windows store for Windows 8 users. Internet access required; fees may apply. Don’t forget, Office isn’t included in Windows 8.

4.0 out of 5 stars A Significant Improvement Over Windows 8.0 20 Oct 2013
Edition:8.1 Full Version
[2014-04-02 read my added comments re Windows 8.1 Update at the end of this review]

Nearly a year ago (on 2012-10-26 to be exact) I made a review of Windows 8 under a title "Will Windows 8 Flop or Fly?". As a Windows user for many years, I was baffled by what Microsoft was up to and I chose an eye-catching title to express my bewilderment of how Microsoft got itself into alienating a significant part of its loyal customers. One year on and now we know the truth and the [self-inflicted] damage done to Microsoft.

My review then didn't catch much attention - it was lost under the very bottom pile of reviews with a tiny 22 helpful votes from 32 people who bothered to read it, despite the fact that that review was one of the first two or three to appear on Amazon on the day Windows 8 was released.

As I said before, and repeating it now, Windows 8 (and the updated version 8.1) has so many desirable features, most importantly it is fast and refined in many respects. The only major trouble is making the User Interface the same for desktop/laptop and mobile computers. The fact is that touchscreen is well suited to tablets and mobile phones (i.e., hand-held mobile computers), while non-mobile computers such as desktops and laptops need to be supported by a navigational menu system as existed in Windows 7 and its predecessors (a.k.a. Start Menu). Imagine visually sifting through randomly placed square icons to locate an App on a Start Page, as opposed to a navigation based on alphabetical order and logical organisation-by-folders of program shortcuts.

Edition:8.1 Full Version
The initial portion of this review addresses the final stage of an progressive upgrade from Windows 7 with an intermediate step --lasting one year-- at Windows 8 before progressing to Windows 8.1.

Bottom line up front: If you are a power user of Windows 7, and you can keep running your current hardware with a Windows 7 variant: I can't offer a single compelling reason to make this change. If you're already using Windows 8, proceeding with the evolution to Windows 8.1 will provide a marginal improvement to the user experience due to the return --sort of-- of the Start button (with much less functionality than in earlier versions of Windows) and the option to boot directly into the desktop (bypassing the clunky "Charms" Metro start page).

I've made this upgrade to two computers. For a desktop computer that met the full Windows Store system requirements, I proceeded with the upgrade from Windows 8 from the Store. A netbook I installed Windows 8 on did not have sufficient display resolution to install 8.1 directly from the Windows Store, so I had to run the installation separately via a downloadable 8.1 installer application.

The good news: In both installation cases, The Windows 8 to 8.1 upgrade was issue free (which mirrored the earlier Windows 7 to Windows 8 upgrade experience for both machines). It retained all of my previously installed OS settings, data files and applications. For the netbook upgrade via the installer program I had to enter my Windows 8 activation key (you still have yours, right?); the upgrade via the Store either trusted me or examined the registry for validity of my install.

The not so good news: once Windows 8.

1.0 out of 5 stars Windows hate 11 April 2014
Edition:8.1 Full Version
My wife is a competent PC user and not stupid. Tonight is her first night with Win 8 and after 40 minutes of struggling she is spitting blood. She spent the last 10 minutes trying to switch the thing off, it is 8.0. Of course when she eventually finds out how to navigate the thing she will be able to get 8.1 and will have a Start button. Then there are those useless tiles. What was wrong with selection from a start menu or desktop? Right now she wants to get on with some work....not spend days relearning how to use an utterly alien OS designed for smart-phones and tablets with small touch screens.

1.0 out of 5 stars Desktop users thrown under the bus 5 April 2014
Edition:8.1 Full Version
If my laptop had come with win 7, I'd already have been working on it for three days. As it is, I'm forced to spend days addressing deficiencies deliberately introduced by microsoft (classic shell, file defaults, etc). White flat windows and scrollbars are hard to use and headache inducing; old proven user interface paradigms aren't available; my desktop experience is disrupted when I open files by taking me to the modal, unnecessary, hard to avoid modern interface. I'm happy to try new things - I'm left wishing the new thing I'd tried is a mac, and considering taking the extra time to upgrade to win 7 despite the time already lost. I always avoided things like linux on my laptop because I didn't want to spend time tinkering, I want to work. Win 8/8.1 forces that on you anyway, for no upside whatsoever.

1.0 out of 5 stars Upgrade?! 10 July 2014
By Mr. Gareth I. Davies VINE VOICE
Edition:8.1 Full Version
Windows XP,
Was always good enough for me,
Windows 8.1,
Has thus far been no fun,
Many basics it lacks,
XP on it ****s,
Want to burn a dvd,
Easy on XP,
Regrets on our necessary upgrade,
Apple was perhaps the choice we should have made.
