HOW TO ACTIVATE WINDOWS 8.1 WITHOUT A 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

Open Windows Store on Windows 8
Find the option to update to Windows 8.1
Select that option and click “Download”
The update files will automatically download and install in the background
Once the update is complete, a prompt will ask you to restart your computer
Restart your computer
Choose “Use Express Settings” once the update screen comes up
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:

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

Pause”

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 8.1 Pro or Ultimate product key.
