Win32_ComputerSystemProcessor - powershell.one

The Win32_ComputerSystemProcessor association WMI class relates a computer system and a processor running on that system.

Methods

Win32_ComputerSystemProcessor has no methods.

Properties

Win32_ComputerSystemProcessor returns 2 properties:

'GroupComponent','PartComponent'

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

Get-CimInstance -ClassName Win32_ComputerSystemProcessor -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_ComputerSystemProcessor 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).

GroupComponent

WIN32_COMPUTERSYSTEM

A Win32_ComputerSystem that describes the properties of the computer system on which the processor is running.

Get-CimInstance -ClassName Win32_ComputerSystemProcessor | Select-Object -Property GroupComponent

PartComponent

WIN32_PROCESSOR

A Win32_Processor that describes the properties of a processor which is running the computer system.

Get-CimInstance -ClassName Win32_ComputerSystemProcessor | Select-Object -Property PartComponent

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 = 'GroupComponent',
              'PartComponent'
Get-CimInstance -ClassName Win32_ComputerSystemProcessor | 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_ComputerSystemProcessor -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_ComputerSystemProcessor -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 PartComponent, GroupComponent FROM Win32_ComputerSystemProcessor 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 PartComponent, GroupComponent FROM Win32_ComputerSystemProcessor WHERE Caption LIKE 'a%'" | Select-Object -Property PartComponent, GroupComponent

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_ComputerSystemProcessor -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_ComputerSystemProcessor -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_ComputerSystemProcessor, 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_ComputerSystemProcessor was introduced on clients with Windows Vista and on servers with Windows Server 2008.

Namespace

Win32_ComputerSystemProcessor 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_ComputerSystemProcessor 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
