How to find License Status of Windows Servers with Powershell

I have publish multiple times different scripts that can use in Powershell to monitoring environments, find details of your Windows Systems and more.

As IT Pro to be compliance you must know every time the License Status of any Software.

It's not easy task to be up to date because of the changes that can be without noted.

For this reason i started to wrote a script that you can identify the License Status of your Windows Servers.

I am in start stage and the script it's not include Handle of Errors and it isn't in GUI Environment.

Right now i have already proceed to handle errors of the powershell script in case that the Windows Server is close or it's not enable the Ws-Man but i don't have include yet in this script until finish it.

So let's start

 

Prerequisites

Before you run the script in your environment you must keep some specs.

The reason is because the Powersell script retrieve all the Computer names from your Active Directory 

Run the following command to install Active Directory Powershell  Module

Install-WindowsFeature RSAT-AD-PowerShell

 

The script you can download from here

Of course you can find this feature 

How the Powershell Script run

After apply all the prerequisites you can run the script and take the License Status of your Windows Servers.

But i believe it will give more value if explain how create this script line by line to help you expanded or change it base on your requirements.

So let's start to explain line by line our code

Create a variable to ask for credentials 

$cred = Get-Credential domain\user

Create an array that will use it to add values while scan the computer names for the licenses

$result1=@()

Save in variable all the computer names of Windows Servers from Active Directory 

$os = Get-ADComputer -Filter 'OperatingSystem -like "Windows Server*"'

 

Start a Loop with ForEach-Object

ForEach-Object{  
 Save only the name property of the Computername in variable
$compn=$os.name

 Create a script that will use in Invoke-command to retrieve 3 properties.


licenses=Only License Product with a Productkeyid. I have add this filter because when query with Get-CimInstance -ClassName SoftwareLicensingProduct will get lot of Licenses related with different applications like Office that will not need it for now.

computername= the computer name of the Windows Server

licensestatus= The License Status of the Product.    

In the license status you will see a number. The number has a description which is the status of the license.

Find the table here from Microsoft Site

Value Description
0 Unlicensed
1 Licensed
2 OOBGrace
3 OOTGrace
4 NonGenuineGrace
5 Notification
6 ExtendedGrace

 

$Scriptblock=
    {

$licenses=@{
      license= ( Get-CimInstance -ClassName SoftwareLicensingProduct | where {$_.productkeyid} ).Description
      Computername=(Get-CIMInstance Win32_ComputerSystem ).Caption
      licensestatus= ( Get-CimInstance -ClassName SoftwareLicensingProduct | where {$_.productkeyid} ).LicenseStatus
    }

    Create a new Object with the Property $licenses

$r=New-Object psobject -Property $licenses
$r

    }

Include in the array the results while connenct with Invoke-Command and run the $Scirptblock which create above    

$result1+= Invoke-Command -cn $compn -Credential $cred -ScriptBlock $Scriptblock -ArgumentList $compn | Select-Object -property license,Computername,licensestatus -ExcludeProperty PSComputername,RunspaceID     }

Type in screen the results   

$result1| Select-Object -property license,Computername,licensestatus -ExcludeProperty PSComputername,RunspaceID   

After understand how wrote the code you can run and you will get the results with the failed in red lines of the computer names that can't conenct.

As i said in the beginning in my next article i will proceed to handle the errors and improve my script

 

You can find a similar option that can use in the VirtualMetric Application that can use to Monitoring your HYPER-V Environment.

If you are interesting you can find a Review that i have done for the VirtualMetric

Have a nice weekend !!!!
