.SYNOPSIS
   Removes ghost devices from your system
.DESCRIPTION
    This script will remove ghost devices from your system. These are devices that are present but have an "InstallState" as false. These devices are typically shown as 'faded'
    in Device Manager, when you select "Show hidden and devices" from the view menu. This script has been tested on Windows 2008 R2 SP2 with PowerShell 3.0, 5.1, Server 2012R2
    with Powershell 4.0 and Windows 10 Pro with Powershell 5.1. There is no warranty with this script. Please use cautiously as removing devices is a destructive process without
    an undo.
.PARAMETER filterByFriendlyName
This parameter will exclude devices that match the partial name provided. This paramater needs to be specified in an array format for all the friendly names you want to be excluded.
