    <#

    .SYNOPSIS

        Gets OS processes created by SQL Server

    .DESCRIPTION

        Gets OS processes created by SQL Server

        Helps when finding hung sessions with External Wait Types

        https://web.archive.org/web/20201027122300/http://vickyharp.com/2013/12/killing-sessions-with-external-wait-types/

    .PARAMETER ComputerName

        The target SQL Server host computer

    .PARAMETER Credential

        Allows you to login to $ComputerName using alternative credentials.

    .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.
