Windows 8.1 Product Key and Activation Guide

We have included Windows 8.1 product keys in this article. Scroll down to find the activation keys.

Windows 8.1 was released in 2012 and is an upgraded version of Windows 8. Up until 2016, users could upgrade their Windows 7 or Windows 8 license into a Windows 10 one, however that is no longer possible.

Upgrading to Windows 10 will require buying (or finding some other way) a valid Windows 10 license. But if you’re still running Windows 8, you can upgrade to Windows 8.1 for free — there’s no need to pay any additional license fee.

However, if your computer isn’t even running Windows 8, in order to install Windows 8.1 you will need a Windows 8.1 product key.

In this article we have included several free Windows 8.1 product keys.

 

Can I Use My Windows 8.1 Product Key With Windows 10?

When Microsoft first released Windows 10, it allowed Windows 8 (and 8.1) and Windows 7 users to upgrade to Windows 10 for free. However, that grace period has long expired.

Therefore, if you wish to use your Windows 8.1 serial number with a Windows 10 copy, you won’t be able to. You will need a Windows 10 license, which you can buy through Microsoft or a third-party seller.

 

Keys

If you wish to activate your Windows 8.1 copy for free, you can use one of the activation keys we’ve included below. We have included Windows 8.1 Pro and Windows 8.1 Ultimate serial keys.

You don’t need to download anything at all. Simply copy one of these product keys, depending on which version you’re interested in: Windows 8.1 Pro or Windows 8.1 Ultimate.

Windows 8.1 Features

Even though it isn’t the latest MS Operating System, there are still many people that prefer Windows 8.1. Let’s take a look at some of the features that Windows 8.1 offers:

  • New applications.
  • Upgraded music and video applications.

Where To Find Your Windows 8.1 Product Key

Every single Windows 8.1 serial number looks something like this:

PRODUCT KEY: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

There are several places where you can find this 25-character serial number:

  • If your computer came with Windows 8 (or 8.1) preinstalled, you could find your serial key printed on a sticker somewhere on the case.
  • If you’ve purchased your computer from an authorized dealer and can’t find the sticker, contact the dealer for the Windows 8.1 product key.
  • If you’ve purchased a Windows 8 (or 8.1) CD/DVD, the serial number should be in a card inside the product box.
  • If you’ve bought a digital license of Windows 8 (or 8.1), the Windows key should have been sent to the email provided at the time of purchase.
  • If you’ve installed Windows 8 with a product key, but can’t locate it, there are programs online which allow you to retrieve the key.

System Requirements for Windows 8.1

Before using Windows 8.1 you need to make sure that your computer is capable of running it. Unless you’re using a very old computer, then it will most likely run just fine.

For Windows 8.1, MS says you need at least:

  • 2GB RAM
  • 1GHz Processor
  • 20GB HDD Space
  • DirectX 9-capable Graphics Card (either dedicated or onboard)

As long as your computer meets these hardware requirements, you will be able to run Windows 8.1.

 

Activation Procedure

After getting your Windows 8.1 genuine Pro or product key, activating Windows is very simple. Here’s what you need to do:

  1. Close all programs
  2. Click on Start and open “Run”
  3. Enter the text “slui 2” and press enter on the dialogue box that pops up
  4. The activation window will open and you will be asked for your Windows 8.1 product key
  5. Enter one of the Windows 8.1 product keys provided above
  6. Your computer will now automatically try to activate Windows

The whole procedure is that simple and shouldn’t take more than a couple of minutes, although it can vary depending on your internet speed.

 

How to Activate Windows 8.1 Without a Product Key

Windows 8.1 product key

You can also install and activate Windows 8.1 without having a product key. It’s easy, and there are several different methods you can try. However, you should note that it doesn’t always work and that you may have to resort to using one of the Windows 8.1 serial keys we’ve provided above.

Remember that a Windows 8.1 product key will allow you to activate Windows without using any of the following methods.

 

Option 1 – Upgrading From Windows 8

If you already have Windows 8 installed on your computer, you can easily upgrade to Windows 8.1. You won’t need a product key to do so.

 

Before You Begin:

  • Back up your important data
  • Make sure that you have at least 3GB of free space on your computer
  • If you’re using a laptop make sure that you’re plugged into an outlet and not relying on your battery

 

Updating Windows Without a Windows 8.1 Product Key

  1. Open Windows Store on Windows 8
  2. Find the option to update to Windows 8.1
  3. Select that option and click “Download”
  4. The update files will automatically download and install in the background
  5. Once the update is complete, a prompt will ask you to restart your computer
  6. Restart your computer
  7. Choose “Use Express Settings” once the update screen comes up
  8. Sign into your Microsoft account and reinstall your applications

With these steps you should be able to update Windows 8 to Windows 8.1 without having to use a Windows 8.1 Pro or Ultimate product key.

 

Option 2 – Make Your Own Windows Activator

This method allows you to activate your operating system without having to insert a Windows 8.1 product key. This involves creating a .bat file which you will run to activate Windows.

All you need to do is copy some text into a notepad file, change its extension and run it.

Here’s how you do it:

  1. Copy the text below into a text file and save the file on your computer:

Pause”

  1. Right-click the text file and click the “Rename” option to make your script.
  2. Change the name to “activator.cmd”
  3. If you can’t change the file extension from .txt to .cmd, then make sure that you have enabled this setting in your Windows file browser:
    1. Click “View” in the file explorer menu
    2. Go to “File and Folder Options”
    3. Go to “View”
    4. Under “Advanced Settings” you will see the option to check and un-check certain settings
    5. Find “Hide extensions for known file types” and uncheck it to show extensions for all file types
    6. Now you can easily change the extension of the file from .txt to .cmd when you rename it
  4. Right click the now .cmd file and choose “Run as administrator”
  5. The file will run and you will see a window briefly appearing and disappearing on your desktop

Now you just need to wait a few seconds and restart your computer. When it comes back on, check to see if your Windows version is activated. You will most likely have an activated Windows version without having to enter any Windows 8.1 Pro or Ultimate product key.

 

Are These Windows 8.1 Keys for 32-bit or 64-bit versions?

The Windows product keys we have provided work for both 32 and 64-bit versions. Microsoft does not differentiate between the two versions.

The main differences between the two different architectures users will notice are the RAM-cap. A 32-bit Windows version will only be able to handle up to 4GB of RAM. Even if you have more RAM installed, you won’t be using it unless you have a 64-bit version.

Unless you’re using an older computer, you shouldn’t really consider a 32-bit Windows version. But, either way you shouldn’t have to worry about your product key not working on a different-bit version.

As long as you have a Windows 8.1 Pro or Ultimate product key, MS doesn’t care about which bit version you use.

 

Conclusion

After reading this article you’ve successfully activated your Windows 8.1 Pro or Ultimate copy, and without having to spend a single cent. You didn’t even need to download any sketchy activator.

If you constantly find yourself needing Windows 8.1 product keys, remember to bookmark this page: we update the available keys frequently and they’ll always be free.
