How to check your windows product key

If you’re looking for your Windows 10 product key, you can find it by entering a quick command in the Command Prompt. Here’s how—plus a neat little trick for finding the product key using a Windows Registry method.

Find Your Windows 10 Product Key Using the Command Prompt

To find your Windows 10 product key using the Command Prompt, you’ll need to open the command line application with administrative privileges. To do this, type “cmd” in the Windows search bar.

Command Prompt will appear in the search results. Right-click it and select “Run As Administrator” from the window that appears. If prompted, enter your Windows account password.

Once open, copy and paste the following command and then hit the Enter key:

The 25-digit product key will then appear.

Note: This method displays the Windows product key stored in your computer’s BIOS or UEFI firmware. In other words, it shows the original Windows key your computer came with. If you’ve installed Windows with a different key since then (or acquired a digital license), it will be different from the current key in use on your PC. If you want the current key in use on your PC, NirSoft’s ProduKey is a good graphical tool for finding it.

That’s all there is to it. This way is quick, but this isn’t likely a code you’ll remember very easily. If you’d like a faster way of accessing your product key in the future, you can use the Windows Registry method instead.

Find Your Windows 10 Product Key Using a Windows Registry Method

Update: This method is all over the web, but it doesn’t seem to return a real usable key on the latest version of Windows 10. (For example, this script in Microsoft’s TechNet gallery works differently, but also grabs output from “DigitalProductId” in the registry.) As of July 2020, we recommend you skip this section and use the above method instead.

The Windows Registry tip was initially posted by a user (whose account is no longer active) in the Microsoft forum.

First, open Notepad by right-clicking anywhere on the desktop, hovering over “New,” and then selecting “Text Document” from the menu.

How to check your windows product key

Once you bought a genuine Windows, a product key should come with it. You can use this key to activate your Windows easily. However, sometimes, users don’t know their system status and fail in activating Windows. They definitely need a good Windows key checker to help them check the Windows product key and then decide what to do next.

What Is Windows Key Checker

Windows key checker refers to the tools used to check your product key of Windows systems. It’s a good way to judge whether your Windows is genuine or not. According to Microsoft, after you bought a copy of Windows, the corresponding product key will be kept on a label or card inside the box. But what is a Windows product key indeed?

Windows Product Key or Digital License

A product key is actually a 25-character code that can be used to activate Windows directly. It helps you determine whether your copy of Windows is genuine or not and whether your system has been used on more PCs that Microsoft Software License Terms allow or not.

  • Windows 10 activation: in general, your Windows 10 system will be activated automatically with the digital license (called a digital entitlement in Windows 10); you don’t need to type the product key manually.
  • Windows 8.1 & Windows 7: you need to find the product keys contained in the confirmation email you received after purchasing the Windows system or in the box Windows came in. Then, you should enter the correct product key as required.

How to Find Your Windows Product Key

How to check your windows product key

Where do you find your Windows product key? That depends on how you get your Windows system.

  • New PC running Windows: the product key has been already preinstalled on the PC or included on the COA (Certificate of Authenticity) connected to the PC.
  • A copy of Windows 10 from authorized retailer: on a label or card inside the box.
  • A digital copy of Windows 10 from authorized retailer: in the confirmation email or in a digital locker that can be accessed via the retailer’s website.
  • A digital copy from a Microsoft website: in the confirmation email.
  • Upgrade to Windows 10 from Windows 7 or Windows 8.1: a digital license instead of a product key.
  • Windows 10 Store App: a digital license you received.

Please Note, if you are installing Windows 10, you do not need your Product Key once you install the same version (Home, Pro . . . etc.)

Since you previously had Windows 10 installed and activated on that PC during the installation process skip the steps which ask for a product key and select the option ‘I am Reinstalling Windows 10 on this PC’, and activation will not be an issue, your PC will have a digital entitlement stored on the Microsoft Activation Servers

I’m Greg, a volunteer installation specialist and 8 year Windows MVP, here to help you.

If this PC came with Windows 10 then the Product Key is embedded in a chip on the motherboard which can be read with ProduKey as the OEM-BIOS key:

If it’s the free Upgrade there is no Product Key so you would skip it during install and then afterwards it will activate with the Digital LIcense which was permanently assigned to the PC when first Upgraded.

If this is retail Windows 10 then the Product Key should be in the packaging or in your MIcrosoft account if you bought it online in the Store app.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it’s resolved.

A copy of Windows is genuine only if it has been activated using a valid key. When you buy Windows Keys from Microsoft websites or get them from the OEMs, you can be sure that they are genuine. But you need to be careful if you buy them from third-party websites. So are Windows 10 keys that you buy from another site like Amazon, etc., legitimate or legal? That depends!

The major problem why many consumers get a license – which is sold at a very low price – and which later turns out to be invalid is because they may be deactivated product keys or Volume license keys. In this post, we will suggest a couple of ways to check if your Windows Product Licence Key is Genuine or Legit.

How to check if my Windows Key is Genuine

There are different types of keys. Windows 10 keys that consumer buys directly, are usually valid until the life of the machine (Retail and OEM).

There is one more type of key: Volume Licensing (MAK and KMS). Enterprise or big companies buy these keys to activate computers in bulk.

I have seen reports where many third-party sellers have sold these keys to consumers at a cheap price. These keys can be activated on multiple computers or work for a couple of months.

It is best not to purchase a key from someone who is not authorized to sell Windows 10 keys. And if somebody is authorized, and they offering low price, make sure to ask them if the key will work even after reinstallation.

There are two scenarios-

  1. First where you have the key, and you want to check before actually using it.
  2. Second is when you have already used it, but still, want to check.

Let’s take a look at how you can find if your Windows Key is genuine.

1] Use PID checker tools

We have two tools here – The Ultimate PID Checker and Microsoft PID Checker – which you can use to find out if the Windows 10 key is legit. While the Ultimate PID checker works for all versions before Windows 10, the Microsoft PID checker works for Windows 10 and Server 2016 only.

Download Microsoft PID Checker from here or Ultimate PID Checker from here. If the key is not legit or is invalid, the software will give you a response back. It can also be used to check the MAK count.

2] Check Windows Key with Software Licensing User Interface

The “dli” parameter will display current license information with activation status.

The result will also include the type of key (Retail, OEM, MAK, or KMS key). If the License status says “Licensed”, then you do not have a problem. If there is anything else, your key is not valid. Also if you see type as MAK or KMS, and you are a general consumer, you need to connect with the person from whom you bought the key, and get a Retail key.

3] Check Settings & Activation Status

There are few quick ways to check if the key you have used in not legit. The first thing you should is open Settings, and see if there is any warning about activation. If that’s not there, go to Update & Security > Activation and check the status. If there is an error and it doesn’t say that Windows is activated, you have a problem. In short the Windows 10 keys not legit or legal.

Report Windows 10 Activation errors

If your Windows 10 is genuine, but you still receive errors relating to an ingenuine software, you can follow up by using the steps below.

  • Open Administrator command prompt then paste the code below and hit Enter
  • Copy the result and upload to One Drive, then locate the txt file Windows created on your desktop then upload both to One Drive
  • Go to the Microsoft Product Activation Call Center and lay your report.

Let us know if this helped you to figure out if the Windows 10 key is genuine or not.

How to check your windows product key

Microsoft offers Windows 10 licenses in many channels governed by different rules, but for most users, you can only acquire a license through the Retail or Original Equipment Manufacturer (OEM) channel.

An OEM license refers to the license that a manufacturer installs on new devices. If this is your case, the product key isn’t transferable, and you can’t use it to activate another installation. (Unless you’re re-activating a new installation on the same computer.)

A Retail license refers to the license that you acquire when purchasing a copy of Windows 10 from your local store or an online retailer (such as from Microsoft or Amazon). If you have a Windows 10 Retail license, you can transfer the product key to another computer, as long as you deactivate the old device.

A Volume license is designed for a large business, education, and government scenario. Usually, a Volume license allows organizations to use one master product key to activate any installation of Windows 10. Although you can use this license multiple times on different computers, you can’t transfer it with the device when the system changes ownership, and you’re not allowed to activate devices that aren’t part of the organization.

If you’re thinking of reusing the same product key on another computer, or you’re just wondering the type of license installed on your device, you can use the Windows Server License Manager Script (slmgr) command tool to find out.

In this Windows 10 guide, we detail the steps required to find out if the license installed on your device is OEM, Retail, or Volume.

How to check product key type installed on Windows 10

To find out whether your Windows 10 license is OEM, Retail, or Volume, use these steps:

  1. Open Start.
  2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.

Type the following command to determine the license type and press Enter:

How to check your windows product key

Quick tip: You can also use the same command syntax in PowerShell.

  • Confirm the license type with the information available in the Windows Script Host dialog.
  • Once you complete these steps, you’ll know the type of product key that you’re using on Windows 10, which will also determine if you can transfer the license to another computer.

    A few days ago, I happened to come across an interesting question while browsing Microsoft support forums. A PC user wanted to know the edition and version of Windows a product key belongs to so that he can download and install the right version and edition of Windows on his PC.

    Let us assume that you have a bunch of Windows product keys, but you are not sure the version and edition they belong to. Although it’s possible to try them on virtual or physical machines, the approach doesn’t make sense when you have a bunch of keys, and especially if you are not sure if they belong to Windows 7, Windows 8, or Windows 10.

    How to check your windows product key

    That said, if you know that a particular key is for Windows 10, then you can determine the edition of Windows 10 the key belongs to by entering it on a PC running Windows 10 as there are only two editions: Home and Pro. Once the job is done, you can uninstall and deactivate the key if you wish to do so.

    Luckily, there are a couple of ways out there to easily determine the version and edition of Windows a product key belongs to. You can use one of the given below utilities to check the version and edition of Windows you can activate using the product key.

    ShowKeyPlus to check Windows 10 edition a product key belongs to

    ShowKeyPlus is a free software designed to retrieve the product key from registry, BIOS/UEFI, and Windows.old folder. In addition to that, the tool can be used to check the version and edition of Windows a product key belongs to.

    Here is how to use the ShowKeyPlus software:

    Step 1: Visit this page, download the latest available version, extract the zip file to get ShowKeyPlus.exe file, and then run ShowKeyPlus.exe with admin rights.

    Step 2: Once launched, click the option labeled Check product key.

    How to check your windows product key

    Step 3: Enter or paste the product key that you want to know the version and edition of Windows the product key belongs to. The version and edition of Windows operating will be displayed just below the product key field.

    How to check your windows product key

    Ultimate PID Checker to check the edition of Windows 10 product key

    Ultimate PID Checker is another free tool out there to determine the version and edition of Windows a product key belongs to.

    Ultimate PID is not as superior as ShowKeyPlus, as Ultimate PID Checker requires you select a version of Windows to know the edition, unlike ShowKeyPlus, which easily displays both the version and edition upon entering a product key. That is, with Ultimate PID Checker, you might need to do trial and error to know the version of the Windows operating system a product key belongs to.

    Step 1: Download Ultimate PID Checker from here, extract the RAR file either using 7-Zip or WinRAR and then run the executable.

    Step 2: Select the version of the Windows operating system that you believe the product key belongs to, enter the product key, and then click the Go button to know the edition of the product key.

    How to check your windows product key

    If the product key entered doesn’t belong to the selected version of Windows, you will not see the edition it belongs to. In that case, select another version of Windows, and then click the Go button again.

    Okay, I get that part, sort of. I went to this site and ran the .vbs script. The Key that appears is apparently invalid when using ShowKeyPlus:

    What I was hoping to find with ShowKeyPlus was the Windows 7 key which would have been in Windows.old. Naturally, when I upgraded, I ran into odd/ends problems and went with a clean install after the upgrade. Of course, this left not Windows.old from the Windows 7 upgrade, but Windows.old from the Windows 10 install. Retrieving the Product Key from Windows.old in my case only resulted in the same generic key.

    So, back to the Macrium Reflect disc image I made before any upgrade; I was able to mount the disc image on Windows 10 November, go to the Windows/System 32/Config section as one would do by going to Windows.old and retrieve the Windows 7 Product Key with ShowKeyPlus. The program did provide an valid, authenticate key for Windows 7. Other products may work, but I rather doubt it, and this is an odd scenario.

    So with the Windows 7 Product Key intact, it is possible to clean install on any computer as long as I have the Windows 10.iso on USB or DVD? Or something random I would have to try? Or just install Windows 7 and start over.

    The reason I ask: Windows 10 isn’t free if I am giving away a perfectly valid Windows 7 key in order to receive a generic Windows 10 key hard coded into the BIOS. As a consumer, it’s actually pointless to upgrade and say to MS, “Here’s my old key and OS; let me have the new one.” Nothing is “free” in the exchange; it’s a simple trade in. Yes?

    @ Jasray
    You have the same product key as mine because you upgraded from Windows 7/8/8.1 to Windows 10 using the free upgrade. All users who upgraded to Windows 10 for free have the same generic key.

    Don’t get it–have the same Product Key as shown.
