If your boss needs a list of operating systems used by computers in your AD, this may be a good start:
#requires -Version 1 -Modules ActiveDirectory $max = 100 $os = Get-ADComputer -Filter * -Properties OperatingSystem -ResultPageSize $max | Group-Object -Property OperatingSystem -NoElement | Select-object -ExpandProperty Name | ForEach-Object { '"{0}"' -f $_ } $list = $os -join ',' $list # copy list to clipboard $list | clip
This script gets all computer accounts from your AD and groups them by operating system, then produces a list from it. Make sure you play with PageSize because retrieving all computers in a large organization may take a long time.
