I have the following script work in windows 10 but not on windows 7:

$LogTime = Get-Date -Format "MM-dd-yyyy_hh-mm-ss"
$Path1= "TEST\TESTLog_$(get-date -f yyyy-MM-dd).txt"
$AffPBS= Get-Process "LLCService.exe" | Select-Object ProcessorAffinity
$AffLC= Get-Process "LCService.exe" | Select-Object ProcessorAffinity
$AffinityLLCFinal = "LLC  " + $AffPBS
$AffinityLCFinal = "LC   " + $AffLC
$FinalOutput = $LogTime+"  " +$AffinityLLCFinal +"     " + $AffinityLCFinal 
$FinalOutput | Out-File -Append $Path1

I have run the Powershell_ISE as administrator and also set Set-ExecutionPolicy RemoteSigned.

The results I'm getting on Windows 10:

10-09-2017_03-31-10  LLC  @{ProcessorAffinity=63}     LC   @{ProcessorAffinity=63}

THe results I'm getting on Windows 7:

10-09-2017_11-23-26  LLC       LC

It seems like the Get-Process isn't working on Windows Embedded Standard. Is there any other way of doing this.

  • Use WMIC, like `wmic process where name="explorer.exe"` – bjoster Oct 09 '17 at 15:46

    `Get-Process | Format-Table ProcessorAffinity, *` shows empty `ProcessorAffinity` for some processes on my standard _Win-8/64_. Try `Get-Process "*LCService.exe"` and omit `.exe` extension at all: try `Get-Process "*LCService"`. Check `$AffLC.GetType()` and `$AffPBS.GetType()`. – JosefZ Oct 12 '17 at 23:01
  • @JosefZ: Yes you are correct. Please put this as an answer so I can accept it. Thanks. – user75464 Oct 14 '17 at 04:51

Get-Process | Format-Table ProcessorAffinity, *

shows empty ProcessorAffinity for some processes on my standard Windows-8/64bit even in elevated PowerShell (ISE).

Moreover, Process.ProcessName Property (== Name AliasProperty) does not include the .exe extension:

The ProcessName property holds an executable file name, such as Outlook, that does not include the .exe extension or the path. It is helpful for getting and manipulating all the processes that are associated with the same executable file.

Examples

PowerShell_ISE, regular user:

PS D:\PShell> (Get-Process * | 
    Select-Object Name, ProcessorAffinity) | 
        Group-Object -Property ProcessorAffinity | 
            Format-Table -AutoSize                    # merely for better readability

Count Name Group

   28 3    {@{Name=avgui; ProcessorAffinity=3}, @{Name=avguix; ProcessorAffinity=3}, @{N...

PowerShell as administrator:

PS C:\Windows\system32> (Get-Process * |
>>     Select-Object Name, ProcessorAffinity) |
>>         Group-Object -Property ProcessorAffinity |
