    Hi ,
    I am a starter in Power shell scripting..
    I am trying to retrieve the list of OS related and Non -OS related service..from n no. of Servers.
    Do we have any cmdlet for the same, if not.. how I can bifurcate the same.

    As in service console, I can see all Win32 related services are stored on C:\windows\system32
    and any Non-OS like anti-virus or any other application used to store in C:\program\... filed
    Please suggest..

    hey Rob,
    Thanks for heading up..

    Gsv or gmi win32_service will list all services.. including the third party apps too. I wants bifurcation for the same... like win32 servicess and apps services..

    Your problem is identifying the 'non-OS' services. There isn't a flag on the service object to indicate where it came from

    If you use
    Get-CimInstance Win32_Service | select Caption, PathName

    You'll see that many services have a path that starts C:\windows\system32\...
    That's probably your best bet but its not infallible e.g.
    Windows Modules Installer has a path of C:\WINDOWS\servicing\TrustedInstaller.exe

    Thanks Richard..
    Get-CimInstances win32_service is much better option.

    I am using this option for getting a OS and Non -OS services from a list of server.

    function Get-OSandNonOSservices
    [Parameter(Mandatory=$true, Position=0,
    ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)]

    process {
    foreach ($c in $ComputerName) {
    $Osservices = (get-CimInstance Win32_Service -ComputerName $c) | select Caption, PathName | sort-object pathname | where {$_.Pathname -like "C:\Windows\*.*"} | Select Caption
    $NonOsservices = (get-CimInstance Win32_service -ComputerName $c) | Select Caption, PathName | where {$_.PathName -notlike "C:\Windows\*.*"} | select Caption

    new-object psobject -prop @{

    ComputerName = $c
    OSServices = $Osservices
    NonOSServices = $NonOsservices
    cat '.\computername.txt' | Get-OSandNonOSservices | Format-table | out-file -filepath "D:\Test\AllServices.csv"

    but I am not sure why this -computername is not appearing for .. Get-CimInstances win32_service

    The reason is that as you are going through the loop you are overwriting you $ListofOsService and $NonOsServices. When you complete the loop you only have the two objects. Not everything you pulled in the loop.

    Move your Out-File into the loop and add -Append and you will get them all like you intend.
