How to add PSComputerName to Last Logon User Script

Question

I wrote the script below on how to get the last logon users from the registry. I would like to add PSComputerName, last logon time, format it and export to a CSV file, help would really be appreciated .

$computer = Get-Content -path 'C:\Users\Public\Computer\computers.txt'

Invoke-Command -ComputerName $computer -ScriptBlock {

    $regpath = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI'

    $regvalue = Get-ItemProperty -Path $regpath

    $regvalue.LastLoggedOnUser

    $regvalue.LastLoggedOnDisplayName

    }

Answer 1

Maybe something like this....

$computer = Get-Content -path 'c:\temp\Servers.txt'     #'C:\Users\Public\Computer\computers.txt'

$results = Invoke-Command -ComputerName $computer -ScriptBlock {   
     $regpath = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI'
     $regvalue = Get-ItemProperty -Path $regpath

    [PSCustomObject]@{      
       LastLoggedOn = $regvalue.LastLoggedOnUser
       DisplayName  = $regvalue.LastLoggedOnDisplayName
     }
}
$results | Select-Object PSComputerName, LastLoggedOn, DisplayName | export-csv -Path C:\temp\result.csv 

Answer 2

See if something like this works for you:

[array]$computers = Get-Content -path 'C:\Users\Public\Computer\computers.txt'
Invoke-Command -ComputerName $computers -ScriptBlock {
    $regpath = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI'
    Get-ItemProperty -Path $regpath
} |
    ForEach-Object{
        [PSCustomObject]@{
            ComputerName = $_.PSComputerName
            LastLoggedOnUser = $_.LastLoggedOnUser
            LastLoggedOnDisplayName = $_.LastLoggedOnDisplayName
        }
    }

I'm not sure if the PSComputerName property will be present if there's only on item in the $computers variable, that's why I explicitly cast the property an an array.

Hello,

The log-on user’s information is stored in the registry. You can check them out in the following location in the RegEditor app.

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI

Get-ItermProperty is a very useful PowerShell cmdlet that lets you retrieve information from your registry effectively.

$regpath = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI'
$regvalue = Get-ItemProperty -Path $regpath
$regvalue.LastLoggedOnUser
$regvalue.LastLoggedOnDisplayName

To get the information from a remote computer, wrap it up in a Invoke-Command cmdlet.

$computer = Read-Host 'Computer'
Invoke-Command -ComputerName $computer -ScriptBlock {
$regpath = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI'
$regvalue = Get-ItemProperty -Path $regpath
$regvalue.LastLoggedOnUser
$regvalue.LastLoggedOnDisplayName
}

Repeat the process if you want to get the last logged on user information from a group of computers.

Note that

in order to get the PowerShell scripts to work on remote computers, there are two prerequisites that need to be met.

Here's a good link as to what I did with the Select-Object cmdlet:

WinRM needs to be enabled on the remote computer
You need proper credentials to run the script on the remote computer.

I hope this will help you further.

Regards,
