    .SYNOPSIS
    Search Registry path for specific keyword

    .DESCRIPTION
    Search-RegistryHive will search the given path for specifc keywords and output the full path to Registry keys
    that contain that keyword

    .EXAMPLE
    Search-RegistryHive -path 'HKLM:\SYSTEM\ControlSet001\Control\Print\Printers' -searchText $Port

Function Get-WSDPortIP {
<#
    .SYNOPSIS
    Resolve IP Address of a network printer mapped via a WSD port

    .DESCRIPTION
    If a network printer is configured on a computer using a WSD port, Get-WSDPortIP will take the portname of the printer
    which should look something like 'WSD-96d31e...' and search the HKLM registry hive for the particualr key that contains the
    IP Address of the network printer.

    .PARAMETER WSDPort
    Portname of printer(s) configured via WSD

    .EXAMPLE
    Get-WSDPort -WSDPort 'WSD-96d31ef9-e17b-41a4-9adc-ad699617382c.0069'

    Example using a single WSD port identifier

    .EXAMPLE
    Get-wsdport -WSDPort (Get-Printer | Where-Object {$_.Portname -like "WSD*"}).PortName

    Example of use case if there are muultple WSD printers on a computer, the above will get all WSD portnames and resolve
    the IP Address of eachone.

    .NOTES
    Writtren as a helper function for a larger script to query printer information on computers in various OU's and output
    to database so that we can create print queues on a print server and Print mapping GPO's

    Works on PowerShell 3.0 and higher
