function Get-DbaComputerSystem {
<#
.SYNOPSIS
Gets computer system information from the server.
.DESCRIPTION
Gets computer 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 IncludeAws
If computer is hosted in AWS Infrastructure as a Service (IaaS), additional information will be included.
.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.
