Do you need to find your Windows product key? The Windows product key is necessary if you want to install Windows on a different computer or reinstall it on your the same computer. You can find the Windows product key using your computer’s Command Prompt, PowerShell program, or within the Windows Registry. This wikiHow article teaches you how to find your Windows product key so that you can activate Windows.[1]

This method works for all versions of Windows, including Windows 10, Windows 8, and Windows 7. With just a few simple steps, you’ll have your license key in no time, ensuring you can activate or troubleshoot your Windows operating system with ease.
If you need to check your Windows license key using Command Prompt, follow these steps:

Why Checking Windows License Key in Command Prompt is Important
Checking the Windows license key in Command Prompt can be highly beneficial for various reasons. Firstly, it allows you to verify the authenticity and validity of your Windows operating system. This is crucial to ensure that you are using a legitimate copy of Windows and are not unknowingly using counterfeit software.
Secondly, checking the license key can help you troubleshoot issues related to activation or licensing. If you encounter difficulties activating your copy of Windows or if you receive constant activation prompts, verifying your license key through Command Prompt can provide valuable information about the status of your license and help you resolve any activation-related problems.
Additionally, knowing your Windows license key can be essential for system administrators or IT professionals responsible for managing multiple devices. By checking the license key, they can ensure compliance with licensing agreements and easily track the status of licenses across different machines.
In summary, checking the Windows license key in Command Prompt is crucial for verifying the authenticity of your operating system, troubleshooting licensing issues, and facilitating license management in a professional setting.
Method 1: Using the Command Prompt
The Command Prompt provides a straightforward way to check your Windows license key. Follow the steps below:
- Open the Command Prompt by pressing the Windows key + R, typing «cmd,» and hitting Enter.
- In the Command Prompt window, type the command «wmic path softwarelicensingservice get OA3xOriginalProductKey» and press Enter.
- Wait for the command to execute. After a few seconds, the Windows license key associated with your device will be displayed.
- Make a note of the license key for future reference, or take a screenshot for easy retrieval.
By following these steps, you can quickly retrieve your Windows license key using the Command Prompt.
Additional Information: License Key Formats
Windows license keys can have different formats depending on the version and method of acquisition. Some common license key formats include:
| Format | Description |
| 25-character string | The most common format, typically used for Retail or OEM licenses. |
| Digital entitlement | For Windows 10, the license may be associated with a digital entitlement rather than a traditional key. |
| Multiple-use key | Some volume licensing agreements provide a key that can be used on multiple devices. |
It’s important to note that the license key displayed in Command Prompt may not always match the key you see on your product packaging or activation screen. This is because some Windows editions use a generic key during installation and rely on digital entitlements or activation servers to verify and assign the appropriate license key to your device.
Troubleshooting: License Key Not Found
If the Command Prompt displays the message «Not Found» or «No Instance(s) Available,» it means that the license key for your Windows installation could not be found using this method. This can occur in certain scenarios, such as:
- Your Windows version does not store the license key in a retrievable manner.
- The Command Prompt is not being run with administrative privileges. Ensure that you run it as an administrator.
- Your Windows copy is not activated, or you are using an invalid or pirated version.
In case your license key cannot be retrieved through Command Prompt, consider alternative methods such as using third-party software or checking the key in the Windows Registry.
Method 2: Viewing License Key in Windows Settings
If you prefer a graphical user interface (GUI) approach, you can also check your Windows license key through the Windows Settings. Follow these steps:
- Open the Start menu and click on the Settings (gear icon).
- In the Settings window, select «Update & Security.»
- Choose the «Activation» tab from the sidebar.
- Scroll down to the section labeled «Windows specifications.» Here you will find the product key associated with your Windows installation.
- Note down the product key or take a screenshot for future reference.
By following these steps, you can easily view your Windows license key without needing to use the Command Prompt.
Alternative Method: Checking in the Control Panel
In older versions of Windows, you can also check the license key through the Control Panel. Here’s how:
- Open the Start menu and search for «Control Panel.»
- Open the Control Panel and navigate to «System and Security.»
- Click on «System.»
- In the System window, scroll down to the section labeled «Windows activation» or «Windows activation status.» Here you will find the license key associated with your Windows installation.
- Make a note of the license key for future reference.
Note that this method is only applicable for Windows versions prior to Windows 10.
Method 3: Using Third-Party Software
If you prefer a more convenient way to check your Windows license key or if the Command Prompt and Windows Settings methods fail to retrieve the key, you can turn to third-party software. There are several reliable tools available that can scan your system and provide you with the license key information.
Some popular third-party software options for checking Windows license keys include:
- ProduKey by NirSoft
- Belarc Advisor
- ShowKeyPlus
These tools offer a user-friendly interface and can retrieve the license key details from your system quickly.
Considerations when Using Third-Party Software
While third-party software can be useful for retrieving license keys, it’s important to exercise caution and only download software from trusted sources. Be wary of downloading software from unknown or unverified websites to avoid the risk of malware or unauthorized access to your system.
Method 4: Checking in the Windows Registry
The Windows Registry contains a wealth of information about your system, including the license key. Here’s how to check your Windows license key in the Registry:
- Open the Command Prompt by pressing the Windows key + R, typing «regedit,» and hitting Enter.
- In the Registry Editor window, navigate to the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
- In the right pane, look for the entry named «DigitalProductId.» The value data of this entry represents your Windows license key.
- Make a note of the license key or copy it for future reference.
Note that modifying the Windows Registry can have unintended consequences and should only be done by experienced users or professionals. It is recommended to create a backup of your Registry before making any changes.
In conclusion, there are multiple methods to check your Windows license key in Command Prompt or through alternative approaches such as Windows Settings, Control Panel, third-party software, or the Windows Registry. These methods provide different ways to retrieve this critical information and can help you verify the authenticity of your Windows operating system, troubleshoot activation issues, and manage licenses effectively.

Сразу после выхода новой ОС, все стали интересоваться, как узнать ключ установленной Windows 10, хотя в большинстве случаев он не требуется. Тем не менее, если вам все-таки требуется ключ для тех или иных целей, его сравнительно просто определить, как для установленной ОС, так и зашитый производителем в UEFI ключ продукта (они могут отличаться).
В этой инструкции описаны простые способы узнать ключ продукта Windows 10 с помощью командной строки, Windows PowerShell, а также сторонних программ. Заодно упомяну о том, почему разные программы показывают разные данные, как отдельно посмотреть OEM ключ в UEFI (для ОС, которая изначально была на компьютере) и ключ установленной в данный момент системы.
Примечание: если вы произвели бесплатное обновление до Windows 10, а теперь хотите узнать ключ активации для чистой установки на том же компьютере, вы можете это сделать, но это не обязательно (к тому же у вас будет ключ такой же, как и у других людей, получивших десятку путем обновления). При установке Windows 10 с флешки или диска, вас попросят ввести ключ продукта, но вы можете пропустить этот шаг, нажав в окне запроса «У меня нет ключа продукта» (и Майкрософт пишет, что так и нужно делать).
После установки и подключения к Интернету, система будет автоматически активирована, поскольку активация «привязывается» к вашему компьютеру после обновления. То есть поле для ввода ключа в программе установки Windows 10 присутствует только для покупателей Retail-версий системы. Подробнее про такую активацию: Активация Windows 10. А при желании, можно использовать Windows 10 и без активации.
Просмотр ключа продукта установленной Windows 10 и OEM-ключа в ShowKeyPlus
Есть множество программ для описываемых здесь целей, о многих из которых я писал в статье Как узнать ключ продукта Windows 8 (8.1) (подойдет и для Windows 10), но мне больше других приглянулась найденная недавно ShowKeyPlus, которая не требует установки и отдельно показывает сразу два ключа: установленной в текущий момент системы и OEM ключ в UEFI. Заодно сообщает, для какой именно версии Windows подходит ключ из UEFI. Также с помощью этой программы можно узнать ключ из другой папки с Windows 10 (на другом жестком диске, в папке Windows.old), а заодно проверить ключ на валидность (пункт Check Product Key).
Все, что нужно сделать — запустить программу и посмотреть отображаемые данные:
- Installed Key — ключ установленной системы.
- OEM Key (Original Key) — ключ предустановленной ОС, если она была на компьютере, т.е. ключ из UEFI.
Также эти данные можно сохранить в текстовый файл для дальнейшего использования или архивного хранения, нажав кнопку «Save». Кстати, проблема с тем, что порой разные программы показывают разные ключи продукта для Windows, как раз и появляется из-за того, что некоторые из них смотрят его в установленной системе, другие в UEFI.
Скачать ShowKeyPlus можно со страницы https://github.com/Superfly-Inc/ShowKeyPlus/releases/, также с недавних пор приложение доступно для загрузки в Microsoft Store.
Еще две программы, чтобы узнать ключ продукта Windows 10
Если по той или иной причине ShowKeyPlus для вас оказался неподходящим вариантом, можно использовать следующие две программы:
Просмотр ключа установленной Windows 10 с помощью PowerShell
Там, где можно обойтись без сторонних программ, я предпочитаю обходиться без них. Просмотр ключа продукта Windows 10 — одна из таких задач. Если же вам проще использовать бесплатную программу для этого, пролистайте руководство ниже. (Кстати, некоторые программы для просмотра ключей отправляют их заинтересованным лицам)
Простой команды PowerShell или командной строки, для того чтобы узнать ключ установленной в настоящий момент времени системы не предусмотрено (есть такая команда, показывающая ключ из UEFI, покажу ниже. Но обычно требуется именно ключ текущей системы, отличающийся от предустановленной). Но можно воспользоваться готовым скриптом PowerShell, который отображает необходимую информацию (автор скрипта Jakob Bindslet).
Вот что потребуется сделать. Прежде всего, запустите блокнот и скопируйте в него код, представленный ниже.

}
GetWin10Key
Сохраните файл с расширением .ps1. Для того, чтобы сделать это в блокноте, при сохранении в поле «Тип файла» укажите «Все файлы» вместо «Текстовые документы». Сохранить можно, например, под именем win10key.ps1
После этого, запустите Windows PowerShell от имени Администратора. Для этого, можно начать набирать PowerShell в поле поиска, после чего кликнуть по нему правой кнопкой мыши и выбрать соответствующий пункт.
В PowerShell введите следующую команду: Set-ExecutionPolicy RemoteSigned и подтвердите ее выполнение (ввести Y и нажать Enter в ответ на запрос).
Следующим шагом, введите команду: C:\win10key.ps1 (в данной команде указывается путь к сохраненному файлу со скриптом).
В результате выполнения команды вы увидите информацию о ключе установленной Windows 10 (в пункте Installed Key) и предложение сохранить ее в текстовый файл. После того, как вы узнали ключ продукта, можете вернуть политику выполнения скриптов в PowerShell к значению по умолчанию с помощью команды Set-ExecutionPolicy restricted
Как узнать OEM ключ из UEFI в PowerShell
Если на вашем компьютере или ноутбуке была предустановлена Windows 10 и требуется просмотреть OEM ключ (который хранится в UEFI материнской платы), вы можете использовать простую команду, которую необходимо запустить в командной строке от имени администратора.
wmic path softwarelicensingservice get OA3xOriginalProductKey
В результате вы получите ключ предустановленной системы при его наличии в системе (он может отличаться от того ключа, который используется текущей ОС, но при этом может использоваться для того, чтобы вернуть первоначальную версию Windows).
Еще один вариант этой же команды, но для Windows PowerShell
(Get-WmiObject -query "select * from SoftwareLicensingService").OA3xOriginalProductKey
Как посмотреть ключ установленной Windows 10 с помощью скрипта VBS
И еще один скрипт, уже не для PowerShell, а в формате VBS (Visual Basic Script), который отображает ключ продукта установленной на компьютере или ноутбуке Windows 10 и, возможно, удобнее для использования.
