Важно! В этой статье речь будет идти о просмотре серийного номера компьютера средствами операционной системы Windows 10, что не предполагает такие методы, как просмотр надписи на наклейке устройства и поиск информации в BIOS. Поэтому, в случае необходимости, рекомендуем обратиться за помощью к другой статье на нашем сайте. Несмотря на то, что в ней речь идет о ноутбуке, перечисленные способы в большинстве своем будут полезны и для владельцев стационарных компьютеров.
Подробнее: Как узнать серийный номер ноутбука
Способ 1: «Командная строка»
Наиболее распространенный способ просмотра серийного номера устройства — выполнение специального запроса в «Командной строке» операционной системы. Первостепенно необходимо будет запустить саму консоль. Сделать это можно многими способами, например, выполнив поиск по системе. Для этого установите курсор в поисковую строку на панели задач и введите запрос «Командная строка». Затем в результатах выдачи кликните по одноименному приложению.

После того как на экране появится черное окно консоли, необходимо ввести вручную или скопировать приведенную ниже команду и нажать по клавише Enter:
wmic bios get serialnumber
Обратите внимание! Этот способ подразумевает обращение системы к утилите ввода и вывода (BIOS), в которой серийный номер должен быть прописан поставщиком оборудования. Если в консоли после выполнения команды указан «0» (ноль), это означает, что нужных данных нет, тогда этот способ становится попросту бесполезным.
Способ 2: «Windows PowerShell»
«Windows PowerShell» тоже позволяет просмотреть серийный номер компьютера путем ввода специальной команды, более того, в отличие от «Командной строки», доступны две версии запроса.
Для начала следует открыть непосредственно «PowerShell» любым доступным способом. В последних версиях Windows 10 проще всего это сделать через контекстное меню кнопки «Пуск». Для этого сначала нажмите по ней правой кнопкой мыши, а затем щелкните по строке «Windows PowerShell».

После появления окна вызываемого приложения дождитесь, пока отобразится строка запроса, в данном случае это «PS C:\Users\USER>», но у вас она может отличаться. Затем скопируйте и вставьте приведенную ниже команду и нажмите Enter:
Get-WmiObject win32_bios | Format-List SerialNumber
Если после выполнения команды по каким-то причинам серийный номер компьютера не выведется на экран, рекомендуется повторить попытку, только на этот раз отправить другой запрос, приведенный ниже:
gwmi win32_bios | fl SerialNumber
Важно! Как и в случае с «Командной строкой», после выполнения команды в Windows PowerShell следует обращение в BIOS для получения нужной информации. Если ее там не оказалось, в результатах будет отображаться «0» (ноль). В таком случае этот способ выполнения поставленной задачи неэффективен.
Способ 3: Фирменное программное обеспечение
Современные компьютеры зачастую имеют фирменное программное обеспечение для настройки отдельных компонентов устройства и просмотра дополнительной информации о нем. С помощью таких приложений можно узнать в частности и серийный номер. Например, компьютеры от HP поставляются с предустановленной утилитой «HP System Event Utility», которая подходит для выполнения поставленной задачи.
Достаточно просто найти ее в списке приложений меню «Пуск» и запустить. На экране сразу откроется информационное окно, в котором будет находиться серийный номер компьютера.
Примечание! В случае отсутствия фирменной программы на компьютере, загружать ее рекомендуется только с официальных ресурсов производителя компьютера, иначе имеется риск проникновения вредоносного ПО в операционную систему.

On Windows 10, the ability to check the computer serial number can come in handy in many scenarios. For instance, when you need to create an inventory of the devices connected to your home network or organization, or need to contact technical support to troubleshoot a problem, order a replacement part, or check the warranty information.
Usually, you can find the required information on the sticker affixed on the back or bottom of your laptop or desktop, or checking the Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI) on your motherboard. However, if the sticker isn’t available or you don’t want to go through extra steps to access firmware, you can also use PowerShell and Command Prompt to retrieve this information quickly on Windows 10.
In addition, using commands can be useful to automate the process using a script when you need to retrieve the serial information from multiple devices.
In this Windows 10 guide, we’ll walk you through the steps to quickly find your device serial number using command lines.

- How to determine PC serial number using Command Prompt
How to determine PC serial number using PowerShell
To retrieve the serial number of your computer with a PowerShell command, use these steps:
- Open Start.
- Search for PowerShell, right-click the top result, and select the Run as administrator option.
- Type the following command to find out the computer serial number and press Enter:
Get-WmiObject win32_bios | select Serialnumber
- Confirm the SerialNumber information.
- (Optional) Type the following command to determine device serial number and press Enter:
Get-CIMInstance win32_bios | format-list SerialNumber - Confirm the SerialNumber information.
- (Optional) Type the following command to export the serial information to a text file and press Enter:
Get-WmiObject win32_bios | select Serialnumber > PATH\TO\EXPORTIn the command, make sure to replace «PATH\TO\EXPORT» with the path to the text file you want to export the serial number information.For example, this command exports the output to the ComputerSerial.txt file in the C drive:Get-WmiObject win32_bios | select Serialnumber > C:\ComputerSerial.txt
Once you complete the steps, you’ll know the serial number of your desktop or laptop computer.
If you are using the command to export the output, you’ll find the file in folder location you specified. Also, since you exported it as a text format, you can open it with Notepad or any other text editor.

How to determine PC serial number using Command Prompt
To check the device serial number using a Command Prompt command, use these steps:
- Open Start.
- Search for PowerShell, right-click the top result, and select the Run as administrator option.
- Type the following command to find out the computer serial number and press Enter:
wmic bios get SerialNumber
- Confirm the computer serial number.
- (Optional) Type the following command to export the serial information to a text file and press Enter:
wmic bios get SerialNumber > PATH\TO\EXPORTIn the command, make sure to replace «PATH\TO\EXPORT» with the path to the text file you want to export the serial number information.For example, this command exports the output to the ComputerSerial.txt file in the C drive:wmic bios get SerialNumber > C:\ComputerSerial.txt
After you complete the steps, the command will return the serial number without needing to access the BIOS or going behind the device to look for the sticker.
Although these commands will work on any computer, custom-build devices don’t have a serial number. This means that the command output may read «To Be Filled By O.E.M.»
If you’re looking to retrieve the device model number, you can use these instructions.

1. What is a product key finder?
The product key finder is a tool for displaying Microsoft Windows product keys and other important information.
2. Are Windows keys stored in BIOS?
The Windows key is stored in the BIOS and invoked when there is an event that restores your operating system. The BIOS key is used to activate Windows automatically if you use the same edition of Windows.
3. Is the product ID the same as the product key?
They are not. The product ID is used to determine the level of service you are entitled to, whereas the product key is used to pair your license with your PC and validate its authenticity.
4. Is Windows 10 illegal without activation?
The installation of Windows without a license is acceptable. Activating it through unsolicited means without purchasing the key is, however, unlawful.
Although there are third-party tools that let you find your Windows product key, they pose the risk of a privacy breach. Besides, it is also worth considering that you can do it on your own without the need for a third-party tool.
