Windows 8.1 brings some greatly desired new features--a Start button, powerful new included apps, a better browser, and lots more. You can read about some of the best in The Top 6 New Features in Windows 8.1 Preview. But how can you get it? Do you need Windows 8 already to upgrade? Actually, if you're using Windows 8, upgrading is a cinch, but non-Windows 8 users can join the party, too, thanks to a downloadable .ISO disk image file of Windows 8.1. For this article, however, we'll assume you're already running Windows 8.

With this update, Microsoft takes a similar approach to the way Apple now updates OS X—through the App Store. So current Windows 8 users will start the Windows 8-to-Windows 8.1 process through the Windows Store, where they'll see the new OS version prominently promoted, and tap Install. But with this Preview version, there's a little prep work involved, as you'll see below.

And for Windows Pro with Windows Media Center users: Your Media Center will be retained if you upgrade through the Windows Store, but you'll have to reinstall if you upgrade using an ISO file.

Remember that Windows 8.1 Preview, is just that--a preview of software that's still in development. So birthing glitches aren't out of the question. Don't install it on a mission-critical work machine or your primary home PC: bugs and data loss aren't completely out of the question. That said, Microsoft claims it's tested the new OS extensively, and you can bet they wouldn't put it out for the public to install if it were a crashy mess.

You shouldn't have to worry about your programs and devices not working: Microsoft has stated that backward compatibility has been their goal for decades, and that hasn't changed. They've tested it with thousands of apps and devices, but there's always a change of upgrade hiccups—especially for deep-system tools such as antivirus and VPN tools.

Let's get started on upgrading to a new, better Windows 8.

1. Make sure your system meets the requirements.
Microsoft lists the minimum system requirements for Windows 8.1 as follows:

  • Processor: 1 gigahertz (GHz) or faster,
  • RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit),
  • Free hard disk space: 16 GB (32-bit) or 20 GB (64-bit), and
  • Graphics card: Microsoft DirectX 9 graphics device with WDDM driver.

2. Back up.
If there are any files you care about on the intended upgrade machine, the same advice applies as with any operating system upgrade: Back up your PC! You can use Windows's own Recovery Drive feature or a third-party tool such as Acronis Backup & Recovery

3. Decide Between Windows Store and ISO.
Upgrading through the Windows Store is the more straightforward method, and if you're on a Windows RT tablet, it's your only option. The other choice is to download an ISO file and create a bootable DVD or USB drive using that. If you upgrade by booting the ISO, you won't be able to keep Windows settings, personal files, and apps, but upgrading from Windows 8 and the Windows Store you will. Here we'll focus on upgrading through the Windows Store. Those who are comfortable with creating bootable media from .ISO files probably don't need a step-by-step article such as this.

4. Enable the Update.
To get started, head to http://windows.microsoft.com/en-us/windows-8/preview-download (the ISO is available for download from the bottom of this page, too). From here, click or touch the "Get the update" button. This will initiate a download of a very small .msu file that will make the update available on the Windows Store. You can either choose Download and then run it, or just Open.

Get UpdateGet Update

You'll then see a security warning on which you can simply click Open.

Security WarningSecurity Warning

This runs the Windows Update Standalone installer--but note that this isn't the actual OS updater--that comes later. Click Yes to run this system updater. After half a minute or so, you'll see a message saying Installation Complete, with a Restart button. Click that (or you can click the Close button if you're not ready).

You'll go through a typical Windows Update shutdown, and when your system comes back to life, you'll see a bar across the Start screen offering to take you to the Windows Store to install the upgrade.

Upgrading: Steps 5-8

5. Go to the Windows Store.
You'll now be on the Windows 8.1 Store page, just as though it were any new-style app. If you head back to the Store front page, the featured app space will be occupied by the 8.1 Preview ad.

Store PageStore Page

From the Update page in the Store, click or touch the "Download" button. This starts a long multi-gigabyte download, so you may want to go grab a cup of coffee or tea. The progress bar switches messages several times, from Downloading, to Getting Update Ready, to Scanning, to Applying Changes, and Gathering info.

After another reboot, you'll see a colorful fish (a fish has appeared on Windows betas since Windows 7) and more percentage counters. Messages like Getting Devices Ready, Applying PC settings will appear, followed by another reboot. More percentage counters and messages like "Setting up a few more things," and "Getting ready" appear.

6. Sign into Windows.
Once all the progress counters and reboots are done, you'll see the user license agreement. Agree, you don't have much choice if you want the update. Next come the typical Settings options, such as whether updates are automatic. I just use the Express settings. You'll then be asked to sign into your Microsoft Account, but you'll have to verify yourself by having a code sent to a trusted email account or mobile.

Your final choice is whether to use SkyDrive. I recommend allowing this; not only does it let you migrate your PC settings, customizations, and touch apps, but also offers a very convenient, built-in online file storage capability that both the system and other apps can use.

7. Enjoy Windows 8.1.
Finally, you'll see the Windows 8.1 Start screen, which looks identical to the Windows 8 one, except it will have a fish-themed background that demonstrated the new moving Start screen backgrounds of Windows 8.1. But that's just the start of the new features you'll discover.

My Experience

I've been testing PC and mobile software for more than 20 years, focusing on photo and video editing, operating systems, and web browsers. Prior to my current role, I covered software and apps for ExtremeTech and headed up PCMag’s enterprise software team. I’ve attended trade shows for Microsoft, Google, and Apple and written about all of them and their products.

I still get a kick out of seeing what's new in video and photo editing software, and how operating systems change over time. I was privileged to byline the cover story of the last print issue of PC Magazine, the Windows 7 review, and I’ve witnessed every Microsoft misstep and win, up to the latest Windows 11.

I’m an avid bird photographer and traveler—I’ve been to 40 countries, many with great birds! Because I’m also a classical music fan and former performer, I’ve reviewed streaming services that emphasize classical music.

Technology I Use

For everyday work, I use a good-old Dell tower with 16GB of RAM, a 12th-gen Intel Core i7 processor, and an Nvidia RTX 3060 Ti GPU that runs on Windows 11. I pair it with a 4K Lenovo ThinkVision P27u-10 monitor and a Logitech MX Vertical mouse. For offsite work, I use a 2024 Microsoft Surface Laptop with a Qualcomm Snapdragon X Elite processor. Camera-wise, I moved to mirrorless from a Canon EOS 80D with a Canon 70-300mm IS USM lens. I now have a Canon EOS R7 with a 100-400mm lens, but I miss my DSLR for several reasons.

In order of usage, the software I turn to most frequently is the Edge web browser, Slack, Adobe Creative Cloud, Microsoft 365, Firefox, Brave, and WhatsApp. I use the Windows Phone link app to see everything on my Samsung Galaxy S21 Ultra phone, which has excellent telephoto capability.

For fitness monitoring, I have a Fitbit Charge 6 and use an Anker Smart Scale P1. I’m also a streaming fan, so I subscribe to both Amazon Music Unlimited (especially for its Dolby Atmos content) and Qobuz (for its high-res sound quality and classical catalog). I recently added a Vizio 5.1 Soundbar SE, which sounds surprisingly good given its low price. To holler commands instead of using a remote control, I have the Amazon Fire TV Cube in the living room, which lets me verbally tell the TV what I want to watch. It hooks up to an LG B4 OLED TV. I have a Sonos One speaker in my kitchen that also ties in with Alexa, as does the Echo Dot 2 With Clock in my bedroom. For serious listening, I have B&W 601 speakers plugged into a Conrad-Johnson Sonographe amp and preamp, with a Cambridge Audio AXN10 streamer as source. For reading, I also have a Nook GlowLight 3.
