How to find out your Windows 10 Product key that's built into your computer

To find out your Windows 10 Product key that's injected in your computer's motherboard:

Download the latest portable version of RWEverything and launch it as admin


Click on ACCESS > ACPI Tables


Then go to the MSDM Tab:



Now you can use that key to install Windows but do note that if the key is embedded in your computer's motherboard BIOS, then chances are that when you start the Windows installation, it won't even ask you for a key since it will grab the key that's embedded in your computer's motherboard and install the appropriate edition.

So what if your computer's embedded key is Windows Home Edition but you want to install Pro or any other edition from the get go without having to do an upgrade? Then check this thread:

How to select Windows Home or Pro when installing Windows 10

 

Found a new easier method:

Launch Command Prompt as admnin

type: " wmic path SoftwareLicensingService get OA3xOriginalProductKey"

 

Well, neither command prompt or power shell shows diddly on my system and I really really don't like having to run ANY software as admin....
It just isn't prudent ya know.

Howzabout a simple key finder app that runs clean with no fluff about it ?

Tiny program, just flat out shows the install key and not much else.

 

But the thing is, we need to be sure that it is actually reading the Windows product key from the BIOS and not simply from Windows.

Imagine one has Windows 10 Pro installed with his own key and he runs that utility, it may be reading the product key that's registered in Windows, not the actual product key that's injected in the BIOS.

Anyway, if you're paranoid about running popular programs that have existed for more than a decade as an admin such as RWeverything then I can't tell you anything. Use what you're happy with.

This guide is for people who want to do it the proper way. In fact, I would be more comfortable running the well-known RWeverything than using some tool on the internet that may be transmitting your product key somewhere.

 

I use Belarc Advisor to get my key. Although it gives me a lot of other info too.
Is it safe?

 

It's been around for a while. I would use it if there wasn't a better way but there are. You see, RWeverything read the product key directly from the BIOS, it's been there since ages so I trust it. If you just want to display the currently installed key then no need for Belarc Advisor, the above command prompt entry does the job.

 

I use NirSoft's product key viewer.
