How to Find Model Name or Serial Number of Windows 11

Knowing your computer’s model name and serial number can be extremely useful when using Windows 11. These details help you identify your exact device, download the correct drivers, find compatible hardware upgrades, check warranty information, contact technical support, or troubleshoot hardware-related problems.

The model name identifies the particular computer or laptop model, such as Dell Inspiron 15, HP Pavilion 15, Lenovo IdeaPad Slim 3, or ASUS VivoBook. The serial number, sometimes called the service tag on certain computers, is a unique identifier assigned to an individual device.

Windows 11 provides several ways to find this information without opening your computer or checking its original packaging. Depending on your PC manufacturer and configuration, some methods may show both the model and serial number, while others may show only one.

In this guide, you will learn several simple methods to find your Windows 11 computer’s model name and serial number. The methods include using Settings, System Information, Command Prompt, PowerShell, and BIOS or UEFI. You can use whichever method is most convenient for your computer.

Find Model Name or Serial Number in Windows 11

Method 1: Find the Model Name Using System Information

System Information is one of the easiest built-in Windows tools for checking detailed information about your computer.

It can display the system manufacturer, model, processor, BIOS information, Windows version, and other hardware details.

To find your computer model using System Information:

1. Press Windows + R to open the Run dialog box.
2. Type:

msinfo32

3. Press Enter.
4. Wait for the System Information window to open.
5. Make sure System Summary is selected on the left.
6. Look for System Manufacturer.
7. Look for System Model.

The System Model entry is normally the model name or model number of your computer.

For example, you might see:

System Manufacturer: Lenovo
System Model: 82XX

or:

System Manufacturer: Dell Inc.
System Model: Inspiron 15 3520

You may also see a System SKU entry. This can be useful when trying to identify the exact configuration of a particular model.

However, System Information does not always display the serial number in an obvious location. If you need the serial number as well, one of the command-line methods below is usually faster.

Method 2: Find the Serial Number Using Command Prompt

Command Prompt provides a quick way to retrieve the serial number stored in your computer’s firmware.

To use this method:

1. Press the Windows key.
2. Type Command Prompt.
3. Right-click Command Prompt.
4. Select Run as administrator.
5. Enter the following command:

wmic bios get serialnumber

6. Press Enter.

Windows will display something similar to:

SerialNumber
PF3ABC123456

The value underneath SerialNumber is the serial number reported by the computer’s BIOS or firmware.

This method is particularly useful when you need the serial number for technical support, warranty verification, or documentation.

However, on newer Windows 11 installations, the WMIC utility may no longer be available because Microsoft has been retiring it. If you receive a message saying that wmic is not recognized, use PowerShell instead.

Method 3: Find the Model and Serial Number Using PowerShell

PowerShell is another built-in Windows tool that can retrieve your computer’s hardware information.

To find the serial number:

1. Press Windows + X.
2. Select Terminal (Admin) or PowerShell (Admin).
3. Enter:

Get-CimInstance Win32_BIOS | Select-Object SerialNumber

4. Press Enter.

PowerShell should display the serial number stored in the system BIOS.

You can also retrieve the computer model using:

Get-CimInstance Win32_ComputerSystem | Select-Object Manufacturer, Model

The result will show the manufacturer and model.

For example:

Manufacturer    Model
------------    -----
HP              15-dy2xxx

You can retrieve both BIOS serial number and model information together with:

Get-CimInstance Win32_ComputerSystem | Select-Object Manufacturer, Model
Get-CimInstance Win32_BIOS | Select-Object SerialNumber

This is one of the most reliable methods when the information has been correctly recorded in the computer’s firmware.

Method 4: Find the Model and Serial Number Through Windows Settings

Windows 11’s Settings application provides basic device information, although the exact information displayed can vary between computers.

To check it:

1. Press Windows + I to open Settings.
2. Select System.
3. Click About.
4. Look under Device specifications.

You will see information such as:

• Device name
• Processor
• Installed RAM
• System type
• Windows specifications

Depending on the manufacturer and Windows configuration, you may also see manufacturer-specific information.

The About page is useful for identifying the basic specifications of your PC, but it may not display the actual serial number. If you cannot find the serial number there, use PowerShell, System Information, or the manufacturer’s support application.

Method 5: Use System Information to Find Additional Hardware Details

System Information provides more than just the model name.

Press Windows + R, enter:

msinfo32

and press Enter.

Under System Summary, you can find information including:

• System Manufacturer
• System Model
• System Type
• Processor
• BIOS Version/Date
• SMBIOS Version
• Windows Directory
• System Directory
• Boot Device
• Installed Physical Memory
• Available Physical Memory
• Virtual Memory

This information can be particularly useful when troubleshooting Windows 11 or contacting technical support.

If you are trying to identify the exact computer model, pay particular attention to System Manufacturer, System Model, and System SKU.

The System SKU can sometimes provide a more specific identifier than the model name shown elsewhere in Windows.

Method 6: Find the Serial Number in BIOS or UEFI

If Windows cannot display the serial number correctly, you can check your computer’s BIOS or UEFI firmware.

The exact procedure varies between manufacturers.

First, save your work and restart your computer. During startup, repeatedly press the appropriate BIOS or UEFI key. Common keys include:

• F2
• F10
• F12
• Delete
• Esc

Once inside BIOS or UEFI, look for a page such as Main, Information, System Information, or About.

Depending on the manufacturer, you may find entries such as:

Product Name
Model
Serial Number
Service Tag
System SKU

The serial number shown here is generally stored in the system firmware.

Be careful when navigating BIOS or UEFI. You normally do not need to change any settings just to view this information.

If you are unsure about a BIOS setting, do not modify it. Simply locate the system information and exit without saving changes.

Method 7: Check the Physical Device

If Windows and BIOS do not provide the information you need, check the physical computer.

On many laptops, the serial number and model number are printed on a label located:

• On the bottom of the laptop
• Inside the battery compartment on older laptops
• Near the hinge
• On the back of a desktop computer
• On the side or rear of an all-in-one PC

Look for labels containing terms such as:

Model
Model No.
Serial Number
S/N
Service Tag
Product Number

Different manufacturers use different terminology.

For example, some manufacturers use Service Tag instead of simply calling it a serial number.

On desktops, the information may be printed on a sticker attached to the chassis.

Avoid confusing the model number with the serial number. A model number is shared by many computers of the same model, while the serial number is normally unique to your individual device.

Method 8: Check the Manufacturer’s Support Application

Many computer manufacturers install their own support software in Windows.

Depending on your computer, the application may display information such as:

• Model name
• Serial number
• Product number
• Warranty status
• BIOS version
• Driver information

If your computer came from a major manufacturer, search the Start menu for its support application.

For example, the application may be designed to automatically identify your computer and provide driver updates or support information.

This can be convenient because manufacturer applications sometimes provide a more descriptive model name than Windows itself.

However, you should verify important information such as a serial number against the device label or BIOS if you are using it for warranty or service purposes.

Method 9: Use Windows Terminal

Windows Terminal provides another convenient way to run PowerShell commands.

To check the model:

1. Press Windows + X.
2. Select Terminal.
3. Enter:

Get-CimInstance Win32_ComputerSystem | Select-Object Manufacturer, Model

Press Enter.

To check the serial number:

Get-CimInstance Win32_BIOS | Select-Object SerialNumber

Press Enter.

You can also display several useful pieces of information with:

Get-CimInstance Win32_ComputerSystem | Select-Object Manufacturer, Model, SystemType

These commands use Windows’ CIM infrastructure and are preferable on modern Windows 11 systems to relying on the older WMIC utility.

Method 10: Find Your Device Information From the Manufacturer’s Website

If you already know the serial number, you can sometimes enter it on your computer manufacturer’s support website to identify the exact product.

This can provide additional information such as:

• Exact product configuration
• Original specifications
• Driver downloads
• BIOS updates
• Warranty information
• Support documentation

This is particularly useful when the model name displayed in Windows is generic.

For example, Windows might show only a family name or model code, while the manufacturer’s support system may identify the exact configuration.

Always use the official manufacturer’s website when entering your serial number for support or warranty information.

Conclusion

Finding your Windows 11 computer’s model name and serial number is relatively simple, and you usually do not need third-party software.

For the model name, the easiest method is to open System Information by pressing Windows + R, entering msinfo32, and checking System Model.

For the serial number, PowerShell is one of the most convenient modern methods. Open Terminal or PowerShell and run:

Get-CimInstance Win32_BIOS | Select-Object SerialNumber

You can find the model and manufacturer with:

Get-CimInstance Win32_ComputerSystem | Select-Object Manufacturer, Model

If Windows does not provide the correct information, check the computer’s BIOS or UEFI firmware or look for the manufacturer’s label on the physical device.

The model number is useful for finding compatible drivers, accessories, replacement parts, and technical documentation. The serial number is more specific to your individual computer and is commonly used for warranty claims, repairs, and manufacturer support.

If you are preparing your PC for repair or support, it is a good idea to record both the manufacturer, model number, and serial number so you can quickly provide the correct information when required.
