If you wish to install Windows 8 on your computer, then you will need a Windows 8 product key. In this article we have compiled a list of Windows 8 serial keys, as well as everything you need to know about Windows 8.
Scroll down to the bottom of the article to find the activation keys. They’re completely free and you won’t need to download anything.
Why Use Windows 8?
Microsoft’s Windows 8 (or its latest iteration, Windows 8.1) provides a feature-rich environment, packed in an elegant user interface. It’s not as sleek as Windows 10, but it’s less resource intensive.
Some of Windows 8 best features are easy gestures, live tiles, an enhanced lock screen and the possibility of conducting system-wide searches with just a few clicks.
Bundled with the fact that it’s lower demanding than Windows 10 and that Windows 8 product keys do not work with Windows 10, Windows 8 is still a great option for many people.
To install this version of Windows, you will need an activation key. Just keep scrolling down until you find our free Windows 8 serial key list.
What is a Windows 8 Product Key?
A Windows 8 product key is a 25-character code used to verify Windows’ authenticity and to activate it.
The unique serial key allows Microsoft to verify that your license hasn’t been used on more computers than the license terms allow.
Windows 8 product keys should look something like this: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.
Free Windows 8 Ultimate Product Keys
Several websites provide outdated Windows 8 ultimate activation keys. Those keys will not work more than half of the times. Others require you to register, download something, or to jump through several hoops in order to get your Windows 8 product key.
Here you won’t have to do anything else. Just choose one of the available Windows 8 Ultimate serial keys, copy it and you’re good to go.
On the rare occasion that a key does not work (either due to being flagged or being used by someone else), check back at a late date. We update our Windows 8 Ultimate activation key list frequently.

Where to Find a Windows 8 Product Key
There’s a chance you might already have a legitimate Windows 8 product key. If you do, but can’t seem to find it, you need to look for it in the right place.
Here are the usual Windows 8 activation key locations:
Inside The Box
If you’ve bought a retail version of Microsoft Windows (on a CD/DVD), then the serial key will be located on a card inside the box.
It’s a good idea not to throw the activation key away after you use it: you never know when you might need it!
In Your Email
If you’ve bought Windows 8 through the Microsoft store, or any other MS retailer, then the product key will be on the email you’ve provided at the time of purchase.
Search your email’s inbox for keywords, such as “Microsoft”, “Windows 8” or “Product Key”, if you can’t seem to find it. When you finally do, remember to save that email for retrieving your Windows 8 serial key whenever you need to.
On a Sticker on Your Computer’s Case
If you’ve bought a computer that already came with Windows 8 preinstalled, then the serial key will be on a sticker somewhere on the computer’s case.
Some times, the sticker is located at the top of the case. Other times it’s at the back. It’s not that hard to miss, and should contain the 25-character serial key.
If you can’t seem to find the sticker, then it might be a good idea to contact your computer’s manufacturer. If you’ve bought a legitimate Windows 8 activation key, then they will need to supply it to you.
Lost Windows 8 Product Key
If you can’t seem to find your Windows 8 product key, there are a few ways you can try to retrieve it.
- You can contact Microsoft directly and provide them with information regarding your activation key purchase. If everything checks out, they will resend you the serial key.
- If you’ve bought a computer with Windows 8 preinstalled, you can contact your PC’s manufacturer for the serial key. If you follow this step, you might need to provide sufficient hardware information.
- You can download one of the many available product key finders applications, but you need to be wary regarding malware. These types of applications will search the Windows Registry for the key.
If your computer is activated and you just want to know what’s your serial key, you can do it via the command prompt. It’s very easy to do and doesn’t require you to download anything at all. Here’s how you do it:
- Open “cmd” with administrator privileges, either by hitting the Windows key + X or by typing “cmd” in the Start menu.
- Type in the following, hitting enter afterwards: “wmic path softwarelicensingservice get OA3xOriginalProductKey”.
- You will get the 25-character XXXXX-XXXXX-XXXXX-XXXXX-XXXXX serial key.
How to Activate Windows 8 For Free
The most obvious manner of activating Windows 8 without spending a cent is by using one of the activation keys we have supplied below. However, there are also ways of activating Windows for free and without using a serial key.
The best way of doing so is by using a Windows activator. However, MS doesn’t supply these kinds of activators, and there’s a chance you might download malware if you look for them online.
Luckily, it’s pretty easy to make your own Windows 8 activator. 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:

- Right-click the text file and click the “Rename” option to make your script.
- Change the name to “activator.cmd”
- 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:
- Click “View” in the file explorer menu
- Go to “File and Folder Options”
- Go to “View”
- Under “Advanced Settings” you will see the option to check and un-check certain settings
- Find “Hide extensions for known file types” and uncheck it to show extensions for all file types
- Now you can easily change the extension of the file from .txt to .cmd when you rename it
- Right click the now .cmd file and choose “Run as administrator”
- 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 Ultimate product key.
Windows 8 Ultimate 32-Bit vs. 64-Bit
As you can see, different Windows 8 versions (32 and 64 bit) have different serial keys. You might be wondering which type of serial key you should use, or which type of Windows is better.
The thing you need to know is that the main difference between the two different architectures is the RAM cap. A 32-bit version of Windows 8 will only be able to handle up to 4GB of RAM.
If you have more than 4GB of RAM installed on your computer, you won’t be able to benefit from it unless you have a 64-bit version of Windows 8.
There’s no way to change from a 32-bit system into a 64-bit one via software download, or fiddling with Windows options. The only way to change from 32 to 64-bit (or vice-versa) is by reinstalling Windows 8, using the appropriate version.
Unless you’re using a very old computer, you shouldn’t consider a 32-bit Windows version. However, if that’s the version you have, don’t worry about it: we have 32-bit serial keys as well.
Although we recommend using a 64-bit version of Windows 8 Ultimate, most users won’t really notice any difference between the two versions.
With this article you are able to successfully activate your copy of Windows 8 Ultimate, without having to spend any money or download anything.
