Windows – Powershell Get Active logged in user in local machine

powershelluserswindows

I am trying to get currently logged in users who has active session.

In the task manager, the list is crystal clear that there are two user sessions and one is active.

I want to query the same via Powershell.
I tried few of the available commands
Get-WmiObject Win32_LoggedOnUser | Select Antecedent -Unique which lists lot more users than I can even see [domain joined computer]

I am looking for the query which can give results exactly like Task Manager.

The issue with Get-WmiObject Win32_LoggedOnUser | Select Antecedent -Unique is that it shows all sessions even those that have been closed since the last time the computer rebooted. The easiest way to poll sessions is unfortunately using the old executable query.exe.

You can convert the output of query.exe to objects using a bit of regex:

$Computer = $env:COMPUTERNAME
$Users = query user /server:$Computer 2>&1

$Users = $Users | ForEach-Object {
    (($_.trim() -replace ">" -replace "(?m)^([A-Za-z0-9]{3,})\s+(\d{1,2}\s+\w+)", '$1  none  $2' -replace "\s{2,}", "," -replace "none", $null))
} | ConvertFrom-Csv

foreach ($User in $Users)
{
    [PSCustomObject]@{
        ComputerName = $Computer
        Username = $User.USERNAME
        SessionState = $User.STATE.Replace("Disc", "Disconnected")
        SessionType = $($User.SESSIONNAME -Replace '#', '' -Replace "[0-9]+", "")
    } 
}

Which will give you output like this:

ComputerName Username SessionState SessionType
------------ -------- ------------ -----------
BSMITH-LT    bobsm    Active       console

Taking it a lot further in to a function:

function Convert-QueryToObjects
{
    [CmdletBinding()]
    [Alias('QueryToObject')]
    [OutputType([PSCustomObject])]
    param
    (
        [Parameter(Mandatory = $false,
                   ValueFromPipeline = $true,
                   ValueFromPipelineByPropertyName = $true,
                   Position = 0)]
        [Alias('ComputerName', 'Computer')]
        [string]
        $Name = $env:COMPUTERNAME
    )

    Process
    {
        Write-Verbose "Running query.exe against $Name."
        $Users = query user /server:$Name 2>&1

        if ($Users -like "*No User exists*")
        {
            # Handle no user's found returned from query.
            # Returned: 'No User exists for *'
            Write-Error "There were no users found on $Name : $Users"
            Write-Verbose "There were no users found on $Name."
        }
        elseif ($Users -like "*Error*")
        {
            # Handle errored returned by query.
            # Returned: 'Error ...<message>...'
            Write-Error "There was an error running query against $Name : $Users"
            Write-Verbose "There was an error running query against $Name."
        }
        elseif ($Users -eq $null -and $ErrorActionPreference -eq 'SilentlyContinue')
        {
            # Handdle null output called by -ErrorAction.
            Write-Verbose "Error action has supressed output from query.exe. Results were null."
        }
        else
        {
            Write-Verbose "Users found on $Name. Converting output from text."

            # Conversion logic. Handles the fact that the sessionname column may be populated or not.
            $Users = $Users | ForEach-Object {
                (($_.trim() -replace ">" -replace "(?m)^([A-Za-z0-9]{3,})\s+(\d{1,2}\s+\w+)", '$1  none  $2' -replace "\s{2,}", "," -replace "none", $null))
            } | ConvertFrom-Csv

            Write-Verbose "Generating output for $($Users.Count) users connected to $Name."

            # Output objects.
            foreach ($User in $Users)
            {
                Write-Verbose $User
                if ($VerbosePreference -eq 'Continue')
                {
                    # Add '| Out-Host' if -Verbose is tripped.
                    [PSCustomObject]@{
                        ComputerName = $Name
                        Username = $User.USERNAME
                        SessionState = $User.STATE.Replace("Disc", "Disconnected")
                        SessionType = $($User.SESSIONNAME -Replace '#', '' -Replace "[0-9]+", "")
                    } | Out-Host
                }
                else
                {
                    # Standard output.
                    [PSCustomObject]@{
                        ComputerName = $Name
                        Username = $User.USERNAME
                        SessionState = $User.STATE.Replace("Disc", "Disconnected")
                        SessionType = $($User.SESSIONNAME -Replace '#', '' -Replace "[0-9]+", "")
                    }
                }
            }
        }
    }
}

and now you can do things like: Get-ADComputer -Filter {Name -like "SERVER*"} | Convert-QueryToObjects | ? {$_.SessionState -eq 'Active'}
