@T-0885
Thanks for your posting on Q&A.

We could run the below PowerShell script in DC and print the OperatingSystemVersion to identify the OS version. Here is a screenshot in my lab for your reference:

 Get-ADComputer -SearchBase 'OU=US,DC=msnoob,DC=com' -Filter * -Properties * | FT Name, OperatingSystem, OperatingSystemServicePack, OperatingSystemVersion -Wrap -Auto

We have to import the Active Directory Module for Windows PowerShell with the following command before running the above script to query the OS Version:

 Import-Module activedirectory

Best regards,
Rita

Thanks for your post ! Could you also advise how export results to file? I add out-file C:\temp\kompy.txt -Append at end but it print nothing

$data = Get-ADComputer -SearchBase 'OU=test,DC=test,DC=local' -Filter -Properties | FT Name, OperatingSystem, OperatingSystemServicePack, OperatingSystemVersion -Wrap -Auto
if($data){
out-file C:\temp\kompy.txt -Append
}

Please try the following PowerShell script:

Get-ADComputer -Filter -Properties | FT Name, OperatingSystem, OperatingSystemServicePack, OperatingSystemVersion -Wrap -Auto | Out-File -FilePath C:Temp\file.txt

Note that remember to create a new folder named Temp included a txt file named with file.txt in the following path before you run the above command:
C:\Windows\System32
