#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Get-DbaOperatingSystem { <# .SYNOPSIS Gets operating system information from the server. .DESCRIPTION Gets operating system information from the server and returns as an object. .PARAMETER ComputerName Target computer(s). If no computer name is specified, the local computer is targeted .PARAMETER Credential Alternate credential object to use for accessing the target computer(s). .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: ServerInfo, OperatingSystem Author: Shawn Melton (@wsmelton | http://blog.wsmelton.info) Website: https: //dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaOperatingSystem .EXAMPLE Get-DbaOperatingSystem Returns information about the local computer's operating system .EXAMPLE Get-DbaOperatingSystem -ComputerName sql2016 Returns information about the sql2016's operating system #> [CmdletBinding()] param ( [Parameter(ValueFromPipeline = $true)] [Alias("cn", "host", "Server")] [DbaInstanceParameter[]]$ComputerName = $env:COMPUTERNAME, [PSCredential]$Credential, [Alias('Silent')] [switch]$EnableException ) process { foreach ($computer in $ComputerName) { Write-Message -Level Verbose -Message "Connecting to $computer" $server = Resolve-DbaNetworkName -ComputerName $computer.ComputerName -Credential $Credential $computerResolved = $server.FullComputerName if (!$computerResolved) { Write-Message -Level Warning -Message "Unable to resolve hostname of $computer.
