Changing default build in NAV Server Administration Tool

When keeping and maintaining NAV Server Services with few different builds on one machine following script may be helpful if you want to create/manage NAV Server with certain build:

$nstDefaultPath = "C:\Program Files\Microsoft Dynamics NAV\71\Service" <#(path to old build)#>
$nstPath = "C:\Program Files\Microsoft Dynamics NAV\71 - Build 37563\Service" <#(path to new build)#>

set-itemproperty -path "HKLM:\SOFTWARE\Microsoft\Microsoft Dynamics NAV\71\Service" -name "Path" -value $nstPath
