Version
Data type: string
Access type: Read-only
Qualifiers: MappingStrings ("WMI")

Processor revision number that depends on the architecture.

Example: Model 2, Stepping 12

VirtualizationFirmwareEnabled
Data type: boolean
Access type: Read-only
Qualifiers: MappingStrings ("WMI")

If True, the Firmware has enabled virtualization extensions.

Windows Server 2008 R2, Windows 7, Windows Server 2008, and Windows Vista:  This property is not supported before Windows 8 and Windows Server 2012.

VMMonitorModeExtensions
Data type: boolean
Access type: Read-only
Qualifiers: MappingStrings ("WMI")

If True, the processor supports Intel or AMD Virtual Machine Monitor extensions.

Windows Server 2008 R2, Windows 7, Windows Server 2008, and Windows Vista:  This property is not supported before Windows 8 and Windows Server 2012.

VoltageCaps
Data type: uint32
Access type: Read-only
Qualifiers: MappingStrings ("SMBIOS|Type 4|Processor Information|Voltage"), Units ("volts")

Voltage capabilities of the processor. Bits 0-3 of the field represent specific voltages that the processor socket can accept. All other bits should be set to 0 (zero). The socket is configurable if multiple bits are set. For more information about the actual voltage at which the processor is running, see CurrentVoltage. If the property is NULL, then the voltage capabilities are unknown.

5 (1)

5 volts

3.3 (2)

3.3 volts

2.9 (4)

2.9 volts

Remarks

On a multiprocessor computer, one instance of the Win32_Processor class exists for each processor.

To determine the total number of processor instances associated with a computer system object, use the Win32_ComputerSystemProcessor association class.

To determine if hyperthreading is enabled for the processor, compare NumberOfLogicalProcessors and NumberOfCores. If hyperthreading is enabled in the BIOS for the processor, then NumberOfCores is less than NumberOfLogicalProcessors. For example, a dual-processor system that contains two processors enabled for hyperthreading can run four threads or programs or simultaneously. In this case, NumberOfCores is 2 and NumberOfLogicalProcessors is 4.

The Win32_Processor class is derived from CIM_Processor.

Examples

The WMI Information Retriever VBScript code example on the TechNet Gallery uses the Win32_ComputerSystemProcessor class to retrieve processor information from a number of remote computers.

The Get-ComputerInfo - Query Computer Info From Local/Remote Computers - (WMI) PowerShell sample on TechNet Gallery uses a number of calls to hardware and software, including Win32_ComputerSystemProcessor, to display information about a local or remote system.

The Multithreaded System Asset Gathering with Powershell PowerShell example on TechNet gallery uses a number of classes, including Win32_ComputerSystemProcessor, to retrieve data from a system.

The following VBScript code example retrieves data about the operating system version and the processor it is running on from Win32_Processor, Win32_ComputerSystem, and Win32_OperatingSystem. This example requires Windows Vista or later.




strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
 & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")


Set colOSes = objWMIService.ExecQuery("Select * from Win32_OperatingSystem")
For Each objOS in colOSes
  Wscript.Echo "Computer Name: " & objOS.CSName

  Wscript.Echo "Operating System"
  Wscript.Echo "  Caption: " & objOS.Caption 'Name
  Wscript.Echo "  Version: " & objOS.Version 'Version & build

Set colCompSys = objWMIService.ExecQuery("Select * from Win32_ComputerSystem")
For Each objCS in colCompSys
  WScript.Echo "  NumberOfProcessors: " & objCS.NumberOfProcessors
  WScript.Echo "  NumberOfLogicalProcessors: " & objCS.NumberOfLogicalProcessors
  WScript.Echo "  PCSystemType: " & objCS.PCSystemType
Next

Set colProcessors = objWMIService.ExecQuery("Select * from Win32_Processor")
For Each objProcessor in colProcessors
  WScript.Echo "  Manufacturer: " & objProcessor.Manufacturer
  WScript.Echo "  Name: " & objProcessor.Name
  WScript.Echo "  Description: " & objProcessor.Description
  WScript.Echo "  ProcessorID: " & objProcessor.ProcessorID

  WScript.Echo "  Family: " & objProcessor.Family
  WScript.Echo "  MaximumClockSpeed: " & objProcessor.MaxClockSpeed

The following VBScript code example shows how to use Win32_Processor to determine the computer architecture.


Set objProc = GetObject("winmgmts:root\cimv2:Win32_Processor='cpu0'")

If objProc.Architecture = 0 Then
    WScript.Echo "x86"
ElseIf objProc.Architecture = 6 Then
    WScript.Echo "Itanium"
Else
    WScript.Echo "Unknown"
End If
