I have put together a robust HP Warrant Lookup PowerShell script. However, I cannot figure out how to get a HP system's product number in an automated process. So...

How can I get HP product number (not the serial number) via PowerShell? Although I would like to do with only built-in out-of-the-box Windows and PowerShell commands, I am open to other ideas. In the end, the ultimate goal is retrieve the product number in the most reliable and least invasive way possible (i.e. installing 3rd software).



Get-WmiObject Win32_ComputerSystem | Select-Object OEMStringArray


{ABS 70/71 79 7A 7B 7C, CMS v01.4A, HP_Mute_LED_0, www.hp.com}

... But expecting to find XT908UT#ABA

  • Is the product number you were expecting listed when running either of the following commands? wmic csproduct list /format:list / wmic computersystem list /format:list

  • Nope. I am pretty sure it's stored in SMBios, but I don't know a reliable way to retrieve it.

    This article says that the number is in the registry at HKLM\HARDWARE\DESCRIPTION\System\BIOS\SystemSKU so can be retrieved in PowerShell. This one says wmic /namespace:\\root\wmi path MS_SystemInformation. Does any of these work for you?

  • On a Dell computer I can use Get-WmiObject Win32_BIOS | Select-Object SerialNumber (I have no HP to test this on).

  • @harrymc - Looks like the registry and MS_SystemInformation is a go! Thanks, you should post it answer answer. I am disappointed in myself because I did come across the same article (registry method) but blew it off.

Here are some methods that work for various computer models.

Method 1 : Registry

The HP product number is in the registry so can be retrieved in PowerShell HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\BIOS item SystemSKU.

More information and script can be found in the article :
How to: Find the HP Product Number of all your HP server using powershell.

Method 2 : root\wmi – MS_SystemInformation

Class MS_SystemInformation contains the product number in its member SystemSKU.
(Presumably it gets it from the registry as in the first method.)

For more info see Richard Siddaway's Blog.

Method 3 : Class Win32_BIOS

The following fragment finds the product number for some computer makes. Tested on Dell.

Get-WmiObject Win32_BIOS | Select-Object SerialNumber

The Microsoft reference information is found in the article Win32_BIOS class.

    The Win32_BIOS class does have the serial number, but that's different than HP's product number (P/N). Which I have recently discovered is call System SKU by Microsoft and Product SKU by SMBios. The registry and MS_SystemInformation class does store this P/N I am looking for.

This is tested on a HP Laptop. I think HP "Product number" is called SystemSKUNumber in win32_computersystem WMI. Tested on my HP laptop.

Get-WmiObject win32_computersystem | Select-Object SystemSKUNumber

Will result in:


If anyone else comes across this question, be advised, the entirety of win32_computersystem doesn't appear to contain the product number for servers, specifically. I was unable to actually find the information via WMI, but it turns out I was actually given the product number AND serial numbers for a number of servers (the spreadsheet was horribly formatted, so the two fields just looked like one big string until my afternoon coffee kicked in).

$PN = (Get-WmiObject -Namespace Root\wmi MS_SystemInformation -ComputerName $PC -ErrorAction SilentlyContinue ).SystemSKU

Write-host $PN
  • Consider adding some reference to this answer supporting what you state to explain why this works. Aug 1, 2017 at 12:50

Works on Windows 7 & Windows 10 From another user that posted. @harrymc

#Open Powershell and type the following. 
$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $Server)
$regkey = $reg.OpenSubkey("HARDWARE\\DESCRIPTION\\System\\BIOS")
$SystemSku = $regkey.GetValue("SystemSku")


or try


Get-WmiObject -ClassName CIM_System -ComputerName $Server| Select-object -ExpandProperty SystemSKUNumber

$Server can be directly replaced by a ComputerName. example...

Get-WmiObject -ClassName CIM_System -ComputerName PC001 | select SystemSKUNumber

Keep in mind if you are on a domain you may need to provide credentials by either using an invoke-command or -credential parameter.

Get-WmiObject -Credential Domain\UserID -ClassName CIM_System -ComputerName $Server


Invoke-Command -Credential Domain\UserID -ComputerName PC001 -ScriptBlock {Get-WmiObject -Credential -ClassName CIM_System}

if WinRm is not configured on client, you may experience issues.

  • the Get-CIMInstance -ClassName CIM_System | Select-object -ExpandProperty SystemSKUNumber have provided me HP product number 7QE59EA#ACB for local laptop but the HP site has accepted the 7QE59EA only

simply from cmd line:

wmic /namespace:\\root\wmi path MS_SystemInformation
