Win32_ComputerSystemProduct - powershell.one

The Win32_ComputerSystemProduct WMI class represents a product. This includes software and hardware used on this computer system.

Methods

Win32_ComputerSystemProduct has no methods.

Properties

Win32_ComputerSystemProduct returns 8 properties:

'Caption','Description','IdentifyingNumber','Name','SKUNumber','UUID','Vendor',
'Version'

Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:

Get-CimInstance -ClassName Win32_ComputerSystemProduct -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_ComputerSystemProduct exist. This is normal behavior.

Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).

Caption

STRING MAX 64 CHAR

Short textual description for the product.

Get-CimInstance -ClassName Win32_ComputerSystemProduct | Select-Object -Property IdentifyingNumber, Name, Version, Caption

Description

STRING

Textual description of the product.

Get-CimInstance -ClassName Win32_ComputerSystemProduct | Select-Object -Property IdentifyingNumber, Name, Version, Description

IdentifyingNumber

KEY PROPERTY STRING MAX 64 CHAR

Product identification, such as a serial number on software, a die number on a hardware chip, or (for noncommercial products) a project number.

Get-CimInstance -ClassName Win32_ComputerSystemProduct | Select-Object -Property IdentifyingNumber, Name, Version

Name

KEY PROPERTY STRING MAX 256 CHAR

Commonly used product name.

Get-CimInstance -ClassName Win32_ComputerSystemProduct | Select-Object -Property IdentifyingNumber, Name, Version

SKUNumber

STRING MAX 64 CHAR

Product’s stock-keeping unit (SKU) information.

Get-CimInstance -ClassName Win32_ComputerSystemProduct | Select-Object -Property IdentifyingNumber, Name, Version, SKUNumber

UUID

STRING

Universally unique identifier (UUID) for this product. A UUID is a 128-bit identifier that is guaranteed to be different from other generated UUIDs. If a UUID is not available, a UUID of all zeros is used.

This value comes from the UUID member of the System Information structure in the SMBIOS information.

Get-CimInstance -ClassName Win32_ComputerSystemProduct | Select-Object -Property IdentifyingNumber, Name, Version, UUID

Vendor

STRING MAX 256 CHAR

Name of the product’s supplier, or the entity selling the product (the manufacturer, reseller, OEM, and so on).

Get-CimInstance -ClassName Win32_ComputerSystemProduct | Select-Object -Property IdentifyingNumber, Name, Version, Vendor

Version

KEY PROPERTY STRING MAX 64 CHAR

Product version information.

Get-CimInstance -ClassName Win32_ComputerSystemProduct | Select-Object -Property IdentifyingNumber, Name, Version

Selecting Properties

To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.

Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.

Selecting Properties

The code below lists all available properties. Remove the ones you do not need:

$properties = 'Caption',
              'Description',
              'IdentifyingNumber',
              'Name',
              'SKUNumber',
              'UUID',
              'Vendor',
              'Version'
Get-CimInstance -ClassName Win32_ComputerSystemProduct | Select-Object -Property $properties

Limiting Network Bandwidth

If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:

Get-CimInstance -Class Win32_ComputerSystemProduct -Property $property | 
Select-Object -Property $property

Selecting Instances

To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).

The parameter -Filter runs a simple query.

Listing all instances where the property Caption starts with “A”

Get-CimInstance -Class Win32_ComputerSystemProduct -Filter 'Caption LIKE "a%"' 

Using a WQL Query

The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:

Get-CimInstance -Query "SELECT UUID, IdentifyingNumber, Vendor, Description FROM Win32_ComputerSystemProduct WHERE Caption LIKE 'a%'"

Any property you did not specify is still present but empty. You might need to use Select-Object to remove all unwanted properties:
Get-CimInstance -Query "SELECT UUID, IdentifyingNumber, Vendor, Description FROM Win32_ComputerSystemProduct WHERE Caption LIKE 'a%'" | Select-Object -Property UUID, IdentifyingNumber, Vendor, Description

Accessing Remote Computers

To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.

Authenticating as Current User

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_ComputerSystemProduct -ComputerName $list 
$result

Authenticating as Different User

Use a CIMSession object to authenticate with a new identity:

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred

$result = Get-CimInstance Win32_ComputerSystemProduct -CimSession $session

# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session

$result

Requirements

To use Win32_ComputerSystemProduct, the following requirements apply:

PowerShell

Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.

If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.

Operating System

Win32_ComputerSystemProduct was introduced on clients with Windows Vista and on servers with Windows Server 2008.

Namespace

Win32_ComputerSystemProduct lives in the Namespace Root/CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.

Implementation

Win32_ComputerSystemProduct is implemented in CIMWin32.dll and defined in CIMWin32.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\CIMWin32.mof
