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

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 Familiar Programs

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

Your Office. Your Way.

1.0 out of 5 stars Wait for Windows 10 3 Mar. 2015
Edition:8.1 Full Version|Verified Purchase
Following the installation of 8.1 it completely corrupted my boot.ini file sending the PC into a boot loop and totally crashed the BIOS. Reading up about it and reading through TechNet comments it appears this is a common problem with 8.1. (Google "Windows 8.1 boot loop" and you'll see). There doesn't even appear to be any attempt at a fix from Microsoft.
Following my having to update the BIOS, restore to a system restore, re-install Windows, and restore from a system image, the problem was still there. I even had to pull my CMOS battery from the motherboard and still no joy.

Eventually I gave up and re-installed Windows 7 and the problem is fixed.

When it did work, the GUI was pretty much the same as Windows 8 but with a Start menu (hooray!).

My advice is to wait for Windows 10. If you've purchased this then you get a free upgrade to Windows 10 anyway, my only saving grace after purchasing this, as it took me two days to fix the issues I had with it.

1.0 out of 5 stars Run away from windows 8.1. Bugs galore! 17 May 2015
Edition:8.1 Full Version
I really, really hate this software. I got it pre-installed with a new laptop and its awful.

To put it simply- nothing on this software is easy. The side bar pops up 24/7 if you go anywhere near the right hand side, it randomly switches from desktop view to that other weird app version without clicking anything.

I paid for Microsoft 2010 and couldn't use it as it 'isn't compatible' so was forced to buy the new one included with the laptop.
And the most annoying thing for me is the PDF/Photo viewer! You can only view 1 PDF at a time which is absolutely horrendous for a uni student, and what makes it worse is the fact that you cant click it into place on the Desktop next to a word document- it has to be full screen which makes copying and referencing infuriating.

I had to download photo 'apps' to edit and look at photos as windows picture viewer/editor doesn't work on it. and it also keeps randomly uninstalling my anti-virus, so I have to check whether i'm protected 24/7.
It also freezes the task bar when you click it for the very first time when you switch into desktop mode and has to reset the screen before you can use it again.

Bearing in mind I have only had this laptop for a couple of weeks and its annoyed me this much.

This software is for tablets, not computers. Windows massively messed up when they tried to make computers app friendly- i have a tablet for that. STOP changing things that don't need to be changed! Windows 7 was fab.

Definitely would NOT recommend.

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.

By Long-Suffering Technology Consumer TOP 1000 REVIEWER
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.
