Determine if Hyper-Threading is enabled

Matthew Dowst 
Function Check-HyperThreading($ComputerName){
    # Get the Processor information for the computer
    $Proc = Get-WMIObject Win32_Processor -ComputerName $ComputerName
 
    # Determine if hyper-threading is enabled
    $CPUCount = @($Proc).count
    $NumberOfLogicalProcessors = $($Proc | measure-object -Property NumberOfLogicalProcessors -sum).Sum
    $NumberOfCores = $($Proc | measure-object -Property NumberOfCores -sum).Sum
    
    # Output the results as a PS object
    [pscustomobject]@{
        Computer = $ComputerName
        CPUCount = $CPUCount
        NumberOfLogicalProcessors  = $NumberOfLogicalProcessors
        NumberOfCores = $NumberOfCores
        HyperThreading = $($NumberOfLogicalProcessors -gt $NumberOfCores)
 
    }

}
Details
This function will return the process information from a local or remote computer and determine if HyperThreading is enabled. If the number of logical processors is greater than physical processors (cores), then hyperthreading is enabled and the function returns True for HyperThreading.

Example
PS C:\> Function Check-HyperThreading($ComputerName){
>>     # Get the Processor information for the computer
>>     $Proc = Get-WMIObject Win32_Processor -ComputerName $ComputerName
>>     # Determine if hyper-threading is enabled
>>     $CPUCount = @($Proc).count
>>     $NumberOfLogicalProcessors = $($Proc | measure-object -Property NumberOfLogicalProcessors -sum).Sum
>>     $NumberOfCores = $($Proc | measure-object -Property NumberOfCores -sum).Sum
>>     # Output the results as a PS object
>>     [pscustomobject]@{
>>         Computer = $ComputerName
>>         CPUCount = $CPUCount
>>         NumberOfLogicalProcessors  = $NumberOfLogicalProcessors
>>         NumberOfCores = $NumberOfCores
>>         HyperThreading = $($NumberOfLogicalProcessors -gt $NumberOfCores)
>>     }
>> }
>> 
>> Check-HyperThreading -ComputerName $env:COMPUTERNAME



Computer                  : MAT-F0CXE4G
CPUCount                  : 1
NumberOfLogicalProcessors : 4
NumberOfCores             : 2
HyperThreading            : True
