get-process product version remote computer - powershell

Question

If I locally do this I get all the information:
get-process | select-object name,fileversion,company
However, if I do it on a remote computer I only get the process name and all the other fields are blank. Does anyone know why or how to get the same information. I am using a domain admin credential so I should have access to that information.
get-process -computername xcomp123 | select-object name,fileversion,company

Answer 1

You can try this solution:
$Computername = 'Remotehost'
$Session = New-CimSession -ComputerName $Computername
$process = Get-CimInstance -ClassName Win32_Process -CimSession $Session
$col = New-Object System.Collections.ArrayList
foreach ($n in $process){
$exePath = $null
$ExeInfo = $null
$exePath = $n.ExecutablePath -Replace '\\','\\'
$ExeInfo = Get-CimInstance -ClassName Cim_DataFile -Filter "Name = '$exePath'" -ErrorAction SilentlyContinue
[void]$col.add([PSCustomObject]#{
Name = $n.name
FileVersion = $ExeInfo.Version
Company = $ExeInfo.Manufacturer
PSComputername = $n.PSComputername
})
}
Remove-Cimsession $session
$col
Update:
I reduced the code to check for one process only. I assert the referencefile having the same name, as the process on the client computers. You might change that for your needs.
You can specify multiple computers at $computername, so you do not have to run the code over and over again.
#region Reference file
$RefFile = Get-item "\\x123\c$\program files\prog\winagent\file.exe"
#endregion
#region remote file
[string[]]$Computername = 'Remotehost1', 'Remotehost2'
$Processname = $RefFile.Name
foreach ($n in $Computername) {
$Session = New-CimSession -ComputerName $n
$process = Get-CimInstance -ClassName Win32_Process -CimSession $Session -Filter "name = '$Processname'"
$exePath = $process.ExecutablePath -Replace '\\', '\\'
$ExeInfo = Get-CimInstance -ClassName Cim_DataFile -Filter "Name = '$exePath'" -ErrorAction SilentlyContinue
[PSCustomObject]#{
Name = $Processname
FileVersion = $ExeInfo.Version
Company = $ExeInfo.Manufacturer
PSComputername = $n
}
Remove-Cimsession $session
}
#endregion
