ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true)]
[String[]]$ComputerName = $env:COMPUTERNAME
)#End Param
Begin
{
Write-Host "`n Checking Users . . . "
$i = 0
$MyParams = #{
Class = "Win32_process"
Filter = "Name='Explorer.exe'"
ErrorAction = "Stop"
}
}#Begin
Process
{
$ComputerName | Foreach-object {
$Computer = $_
$MyParams["ComputerName"] = $Computer
try
{
$processinfo = #(Get-WmiObject #MyParams)
if ($Processinfo)
{
$Processinfo | ForEach-Object {
New-Object PSObject -Property #{
ComputerName=$Computer
LoggedOn =$_.GetOwner().User
SID =$_.GetOwnerSid().sid} } |
Select-Object ComputerName,LoggedOn,SID
}#If
}
catch
{
"Cannot find any processes running on $computer" | Out-Host
}
}#Forech-object(ComputerName)
}#Process
End
{
}#End
}#Get-LoggedOnUsers

Add a query for the Win32_ComputerSystem class:
Get-WMIObject -Class Win32_ComputerSystem -Computername $Computer | Select UserName
That'll grab the 'active' user, then you can build an object with an 'Active' boolean value.
Here's my implementation:
function Get-LoggedOnUser
{
[CmdletBinding()]
Param
(
[Parameter(Mandatory=$true,
Position=0,
ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true)]
[String[]]$ComputerName
)
Begin
{
$users = $null
$return = #()
}
Process
{
ForEach($Computer in $ComputerName)
{
$activeUser = Get-WMIObject -class Win32_ComputerSystem -ComputerName $Computer -EA stop | select UserName
Try
{
$processinfo = #(Get-WmiObject -class win32_process -ComputerName $Computer -EA "Stop")
If ($processinfo)
{
ForEach($process in $processinfo)
{
[string[]]$users += $process.GetOwner().user| Where{($_ -ne "NETWORK SERVICE") -and ($_ -ne "LOCAL SERVICE") -and ($_ -ne "SYSTEM")}
}
If($Users)
{
ForEach($user in ($Users | Select -unique))
{
If($ActiveUser.username -like "*$user")
{
$Return += New-Object PSObject -Property #{
"User" = $user
"Active" = $true
"Computer" = $Computer
}
}
Else
{
$Return += New-Object PSObject -Property #{
"User" = $user
"Active" = $false
"Computer" = $Computer
}
}
}
}
Else
{
"There are no users logged onto $computer" | Out-Host
}
}
}
Catch
{
"Cannot find any processes running on $computer" | Out-Host
}
}
}
End
{
$Return
}
}
It is worth it to point out that the Win32_ComputerSystem username is only populated if the user is logged in locally, so anyone logged in through remote desktop won't show as 'Active'.
