Reinstall Windows 8.1 Download Free
Update 7/31/2020: Windows 8.1 is long outdated, but technically supported through 2023. If you need to download an ISO to reinstall the full version of the operating system, you can download one from Microsoft here.
If you are still using Microsoft Windows 8.1, we recommend you at least begin considering what OS you will use in the future. It's mid-2020 and Win 8.1 will shuffle off the mortal coil in January 2023. You can still qualify for a free upgrade to Windows 10 if you own a valid Windows 8.1 license, despite the fact that Microsoft formally ended its upgrade program five years ago. Additionally, Windows 10 has the same system requirements as Windows 8.1, so if you can run the latter, you can also run the former.
If you are somehow still stuck on Windows 8.0 and do not want to go to the hassle of a full OS swap, we recommend running Windows Update immediately and downloading all available patches for your system, including the Windows 8.1 update, which will likely be offered to you by default. If you want to download just the Windows 8.1 update files, you can do so here.
Original story below, from 2013:
Windows 8.1 has been released. If you're using Windows 8, upgrading to Windows 8.1 is both easy and free. Powerpoint os x. Chrome official version. If you're using another operating system (Windows 7, Windows XP, OS X), you can either buy a boxed version ($120 for normal, $200 for Windows 8.1 Pro), or opt for one of the free methods listed below. To download and install Windows 8.1 for free, follow the guide below.
How to download Windows 8.1 for free
If you don't want to wait for October 17 or 18, there are two options for downloading Windows 8.1: You can obtain a copy (and a license key) from a friend/colleague with an MSDN, TechNet, or DreamSpark (student) subscription, or you can download a Windows 8.1 RTM ISO from your favorite file-sharing website (The Pirate Bay, Mega, etc.)
Windows Installer 8 Download Iso
While we're not going to write a guide on how to obtain Windows 8.1 RTM from non-official sources, we will at least tell you to check the SHA-1 hash of the ISO that you download to make sure that it's legitimate. If you hit up the MSDN Subscriber Downloads page, and then click Details under the version that you've obtained from elsewhere, you'll find the SHA-1 hash. If you then use File Checksum Integrity Verifier (FCIV) on the ISO, the hash should match. If it doesn't, assume the ISO has been compromised and download another. (But do make sure that you're checking the right SHA-1 hash on the MSDN website; your ISO might be mislabeled).
The other easier, and completely legal, option is to download the Windows 8.1 Preview from Microsoft. It's not as snappy as the final (RTM/GA) build, though, and has quite a few bugs/missing features. Bear in mind that if you go down this road, upgrading to a real version of Windows 8.1 will require a few more steps (discussed in the next section).
How to install Windows 8.1 for free
Windows 8 Installer Download Free
Once you have the Windows 8.1 ISO on your hard drive, the installation process is painless. Before you begin, you should consider backing up your important files and documents, but it's not really necessary. You should also ensure that you have plenty of free hard drive space (20GB+).
If you're already running Windows 8 and you downloaded the RTM ISO from somewhere other than the Windows Store, you can install Windows 8.1 by mounting the downloaded ISO in Explorer by double-clicking it, and then running the installer. If you're on Windows 7, XP, or (bless your soul) Vista, you'll need to burn the ISO to a USB thumb drive or DVD, or mount the ISO using a third-party virtual drive tool, like Magic ISO.
If you already have Windows 8, and you waited for the official release date, installing Windows 8.1 is as simple as visiting the Windows Store and downloading the free update.
In both these cases, the upgrade process should be very smooth, with your apps and settings fully preserved. If you upgrade from Windows 8.1 Preview, however, you will lose your installed apps, unless you first run a cversion.ini removal utility.
