Windows Product Key Cmd | Try A Third-Party Tool

Quick Links

Key Takeaways

• Quickly find your Windows 10 product key by opening Command Prompt with administrative privileges and enter: “wmic path softwarelicensingservice get OA3xOriginalProductKey”.
• If the command-line method doesn’t work for you, use software like NirSoft’s ProduKey or ShowKeyPlus to find your product key.
• Avoid using the Windows Registry method to find your product key, as it may not return a usable key on the latest version of Windows 10.

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.

How to find your Windows product key using Command Prompt (CMD)

1. Type cmd in the Windows 10 search bar.

2. Right-click on Command Prompt, select Run as administrator, and select Yes if Windows asks you to allow access.

3. Type or copy and paste the following command into the Command Prompt:

   wmic path softwareLicensingService get OA3xOriginalProductKey

4. Press Enter. Your 25-character Windows 10 product key should now be displayed (in 5-character sets).

That’s how to find a windows 10 product key in cmd (Command Prompt). You can find your Windows 7 product key in Command Prompt by following the same steps. To open Command Prompt in Windows 7, press the Windows key + R and type cmd into the search box.

Try a third-party tool

Product key finders can locate keys for software that’s already installed. Using one of the methods above to find your key is safer, since giving a company access to your computer leaves you vulnerable to bloatware or even types of malware.

Only use third-party tools you trust. If a third-party tool infects your device, downloading the best free antivirus software can remove it.

Some notable Windows product key finders are MyKeyFinder and Belarc Advisor. These products have free trials but may require additional information or send you ads. Third-party tools can also recover deleted files on Windows and other, more specialized services.

Get your Windows 10 product key: step by step

If you need to find the product key for your Windows 10 installation, you’ve got a few options. The key can be retrieved via the BIOS i.e. the bootloader of your system or the command window. You can also use external software to retrieve your Windows 10 key.

Find Windows 10 product key using third-party solutions

The easiest way to retrieve a Windows 10 product key is to use a special program. Because Microsoft doesn’t currently offer its own solutions, users will have to default to third-party providers such as Belarc which has developed a relevant tool. For example, the Belarc Advisor can be used to read the licensing code from the Registry or BIOS. To find your licensing code, follow these steps:

1. Download the third-party software from the website by filling in your email details
2. Install the Belarc Advisor
3. Start the tool by running it
4. Once installed, the software will automatically generate the product key

Windows 10 key retrieval using CMD

The command line or CMD can be used to gain information about a Windows installation key. However, you may only be able to view the last five digits of a Windows 10 code this way. Here’s how to do it:

Open the command line by searching for “CMD” or “command line.” Select the correct search result. Alternatively, launch a Run window and enter “cmd” to launch it.

Get your Windows 10 product key from BIOS

If your Windows key is stored in the BIOS – the boot software of your Windows PC – you can retrieve it quickly by using the PowerShell program.

Launch the Windows PowerShell by searching for “PowerShell” in the search bar. Select the program and open it. The Windows configuration framework will be launched:

Add the following commands to the PowerShell command line and confirm by hitting “Enter.”

Nếu bạn đang muốn xem lại Key bản quyền Windows đã thêm vào máy tính của bạn thì đây sẽ là một vài cách đơn giản nhất hiện nay.

Sử dụng Command Prompt

Bằng cách sử dụng Command Prompt, có thể tìm thấy bằng công cụ tìm kiếm với tên ‘Command Prompt’ hoặc ‘cmd’, lúc này bạn cần chạy dưới quyền quản trị viên để có thể tiếp tục thao tác. Ngoài Command Prompt bạn cũng có thể sử dụng PowerShell.

Tại giao diện chính của Command Prompt bạn cần nhập dòng lệnh sau:

wmic path softwarelicensingservice get OA3xOriginalProductKey

Sau khi bấm Enter, Product Key của bạn sẽ hiện trên màn hình với 25 kí tự.

Cách làm này sẽ hiển thị product key của Windows nếu như nó được lưu trữ ở BIOS hoặc UEFI Firmware. Hay nói cách khác, cách này sẽ cho bạn xem được key bản quyền đi theo máy còn được gọi là OEM Key. Nếu như bạn đã thêm một Key bản quyền theo một cách khác, ví dụ như là bản digital sẽ cần cách thức khác để có thể tìm thấy được product key.

Sử dụng phần mềm bên thứ ba

Với lệnh phía trên sẽ không hoạt động cho tất cả mọi người dùng và vì vậy, trong trường hợp bạn sử dụng nhưng không thấy được product key thì sử dụng phần mềm bên thứ ba sẽ là giải pháp.

ShowKeyPlus hiện đang là giải pháp thông dụng nhất và có mặt trên Microsoft Store nên bạn hoàn toàn có thể tin cậy sử dụng phần mềm này để kiểm tra product key.

Phần mềm này sẽ hiển thị cùng lúc cả 2 loại là key cài đặt vào máy hoặc là key OEM, nên sẽ khá đầy đủ.

Sử dụng công cụ Windows Registry

Đây là cách làm được người dùng khám phá ra với cách làm cũng khá đơn giản. Bạn cần sử dụng Notepad để tạo một Text Document. Bằng cách thoát ra màn hình Desktop, chọn tạo Text Document, sau đó Copy và Paste đoạn nội dung sau vào trong Notepad.

Set WshShell = CreateObject(“WScript.Shell”)MsgBox ConvertToKey(WshShell.RegRead(“HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId”))Function ConvertToKey(Key)Const KeyOffset = 52i = 28Chars = “BCDFGHJKMPQRTVWXY2346789″DoCur = 0x = 14DoCur = Cur * 256Cur = Key(x + KeyOffset) + CurKey(x + KeyOffset) = (Cur \ 24) And 255Cur = Cur Mod 24x = x -1Loop While x >= 0i = i -1KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutputIf (((29 – i) Mod 6) = 0) And (i <> -1) Theni = i -1KeyOutput = “-” & KeyOutputEnd IfLoop While i >= 0ConvertToKey = KeyOutputEnd Function

Sau khi tạo xong bạn cần Save As > chọn định dạng ở All Files và đặt tên file bất kì với định dạng ‘.vbs’, ví dụ ảnh bên dưới đang đặt là ‘productkey.vbs’

Sau đó bạn chỉ cần mở file .vbs vừa tạo là có thể xem được product key đã thêm vào bên trong máy.

How to find and retrieve your Windows 10 product key

The Windows 10 product key is a dedicated 25-digit, letter, or number code which acts as a product key or code to unlock a software license and install the Windows operating system on your PC. The software can only be unlocked, installed, and used after it is unlocked.

A product key is usually subdivided into multiple parts comprised of a combination of various letters and numbers. Each licensing key is unique and can only be used with a single version of a purchased software. Through a special procedure, the licensing key is tested for its authenticity. The first ever licensing key was used as part of the Windows 95 operating system and was displayed on the installation disc cover. Windows justified the issue of a licensing code by saying that it was trying to avoid illegal usage of its licensed software.

Nowadays, you’ll either need a 25-digit code or a digital license to install Windows. Users without a digital license will need to retrieve their Windows 10 product key.

Search your emails

If you purchased Windows through a retailer, searching in your email for terms such as “product key,” “Windows confirmation,” or “Microsoft activation” could bring up your product key details. If you think you purchased Windows through the Microsoft Store App, searching for “Microsoft Services Agreement” or the email address “[email protected]” might help you find an email correspondence with your Windows 10 or Windows 7 product key.

If you use Gmail, you can search your inbox with specific parameters using Gmail’s search operators. You can search by email sender (from:[name]), recipient (to:[name]), or even terms in the subject line (subject:[microsoft activation key]), for example.

Check your Windows settings

You can also check if you have an active Windows license — and whether it’s a digital license — through the Windows 10 settings.

1. Open the Start Menu and select Settings.

2. Click Updates & Security.

3. Select Activation.

Next to Activation, you’ll see information about your Windows 10 activation status, and whether you have a digital license. You can also change your Windows 10 product key on this screen if you need to.

How to find your Windows Product Key in the Registry Editor

1. Type regedit in the Windows 10 search bar. Click on the Registry Editor. Select Yes if Windows asks you to allow access.

2. In the folder system that displays, navigate to:

   Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

   Each item between backslashes above corresponds to the folders you need to click to find the folder with your Windows product key: the SoftwareProtectionPlatform folder.

   Your product key is listed next to the item named BackupProductKeyDefault.

That’s how to find your Windows 10 product key using the Windows registry. The product key here might be different from the product key found through Command Prompt or PowerShell. That could be because you’ve upgraded or changed your version of Windows. You can find a Windows 7 product key in the registry through the same method.

Find Your Windows 10 Product Key Using a Windows Registry Method

This method is all over the web, but it doesn’t 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.) This method has been defunct since 2020, and we recommend you use the method listed above instead. 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.

Copy and paste this code into Notepad:

Set WshShell = CreateObject(“WScript.Shell”)MsgBox ConvertToKey(WshShell.RegRead(“HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId”))Function ConvertToKey(Key)Const KeyOffset = 52i = 28Chars = “BCDFGHJKMPQRTVWXY2346789″DoCur = 0x = 14DoCur = Cur * 256Cur = Key(x + KeyOffset) + CurKey(x + KeyOffset) = (Cur \ 24) And 255Cur = Cur Mod 24x = x -1Loop While x >= 0i = i -1KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutputIf (((29 – i) Mod 6) = 0) And (i <> -1) Theni = i -1KeyOutput = “-” & KeyOutputEnd IfLoop While i >= 0ConvertToKey = KeyOutputEnd Function

Next, click the “File” tab and select “Save As.”

In File Explorer, set the “Save As Type” dropdown to “All Files” and give your file a name. You can use any name, but it has to be a .vbs file. You can name it something like:

productkey.vbs


Once you’ve entered a file name, save the file.

You can now view your Windows 10 product key at any time by opening the new file.

How to find your Windows 10 product key

This guide aims to assist you in locating the Windows 10 product key although the method and commands may be applicable or similar to other Windows versions.

Within the ‘About your PC’ section of the system control panel, details such as Device IDs and Product IDs are available, but conspicuously absent is information regarding your Windows product key.

Microsoft and its system partners ceased the practice of providing stickers or certificates displaying Windows product keys long ago. Subsequently, Windows activation relies on a digital license linked to your system’s hardware fingerprint.

While this approach simplifies the process of reinstalling, situations may arise where access to the product key is necessary. These can include an OS downgrade or various upgrade projects.

If you find yourself in possession of a PC with an activated copy of Windows 10 and a desire to retrieve the product key, a solution involving a few command prompt entries is both swift and straightforward. We’ve laid out the steps below so you can your Windows 10 product key without any hassle.

How to find your Windows Product key using PowerShell

1. Right-click on the Start Menu.

2. Select Windows PowerShell (Admin). Click Yes if Windows asks you to allow access.

3. Type or copy and paste the following code into PowerShell:

   powershell “(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey”

4. Press Enter. Your 25-character Windows 10 product key should now be displayed (in 5-character chunks).

What about Windows 7?

Anyone running Windows 7 should upgrade to Windows 10. Along with being faster and smoother, Windows 10 is better at managing memory and disk space. If your hard drive is clogged or buggy, see how to use chkdsk in Windows to scan your drive and fix it. It’s possible that upgrading to Windows 10 can improve your hard drive’s health too. Upgrading to Windows 10 can even fix the Windows black screen in some cases.

With Windows 10 you can integrate Microsoft’s OneDrive cloud storage, and get increased security with Windows SmartScreen and Windows Defender.

If you’re wondering how to find a Windows 7 product key, you can do so using Command Prompt or the Registry Editor, as shown above. If you ever want to upgrade to Windows 10 or 11 from Windows 7, you’ll need your Windows 7 product key.

Digital licenseproduct key

If you bought a physical disc or retail copy of Windows 10, you have a product key located somewhere on or inside the original packaging. If you bought Windows 10 online directly from Microsoft, you have a digital license.

If you buy or upgrade Windows 10 directly from Microsoft, you don’t need a Windows 10 product key. Microsoft creates a digital license automatically and stores it on their servers in a process called digital entitlement. A digital license serves the same purpose as a product key, except it’s stored on the operating system itself — you don’t need to re-enter it if you reinstall or upgrade Windows.

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” or “Command Prompt” in the Windows search bar. Command Prompt will appear in the search results. Select “Run As Administrator” from the window that appears. If prompted, enter your Windows account password.

This will also work with PowerShell.

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

wmic path softwarelicensingservice get OA3xOriginalProductKey

The 25-digit product key will then appear.

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. Properly it is called an “OEM Key.” 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. You’ll have to use the next method if you want to find that key.

Things You Should Know

• You can find your Windows product key using the Command Prompt, Powershell, or the Windows Registry.
• If you purchased Windows from a licensed retailer, you can find your Windows key in the box that it came in.
• If you bought a digital version of Windows or an upgrade online or from the Microsoft Store, you should receive your product key in a confirmation email.

Find Your Windows 10 Product Key Using Software

The command-line method above isn’t for everyone, and it doesn’t work if you’re using a product key you purchased rather than one that came with your PC. There are plenty of software solutions out there to show you the current key in use on your PC, but we like both NirSoft’s ProduKey and ShowKeyPlus. ShowKeyPlus is available from the Microsoft Store, and NirSoft’s ProduKey is available from the Nirsoft website.

NirSoft’s ProduKey will probably trigger your antivirus. Because of what ProduKey does — and how it does it — your antivirus thinks it is or could be malicious. As long as you download it from the official site, you don’t have to worry about it. Nirsoft has had a great reputation for a very long time.

ShowKeyPlus will show you both your OEM key and your retail (“installed”) key if you have both. Otherwise, it’ll just display your retail key.

Nirsoft’s UI is more minimalist. Your product key will be displayed to the right of your operating system, in our example we’ve obfuscated our key with a blue box.

That’s all there is to it. This way is quick, but this isn’t likely a code you’ll remember very easily.

When do you have to retrieve your Windows key?

With the launch of Windows 10, product keys have become less important because Microsoft launched digital licenses in 2016. Digital licenses allow for the simple installation of an operating system without requiring a bootable device. The operating system can be activated via your Microsoft account. Even when you’re reinstalling Windows 10, the system detects the license automatically.

You’ll get a digital license if:

• You purchased a new PC with a Windows operating system
• You upgrade Windows 7 or 8 to Windows 10
• You purchase an operating system via the Microsoft Store

If you’ve purchased a digital license, you may be able to view the Windows 10 license and get a product key afterwards.

In the following situations it may be necessary to retrieve the Windows 10 product key:

• You’ve purchased the disc-based Windows 10 version
• You’ve got a digital version of the operating system from an authorized dealer
• You have a volume licensing contract or MSDN subscription

In addition, to deinstall or reinstall another Windows version you might need a Windows 7 product key or Windows 8 product key. However, the steps to retrieve product keys for older Windows versions may differ.

The Short Version

• Press the Windows key and R keys simultaneously
• Type cmd in the run box dialogue you have summoned, and hit the enter key
• In the resulting cmd.exe window, type “wmic path softwareLicensingService get OA3xOriginalProductKey” without the quotation marks
• Press enter, and you should see your Windows 10 product key revealed – copy it for posterity in your favourite notes app, or simply write it down somewhere
