So I downloaded a bunch of files from "the way back machine" site and I needed to update the hard-coded links to be relative site links. The following little script did it for me.

{{{#!highlight powershell

$files = ls Level*.html
foreach ($item in $files) {
    (Get-Content -path $item) | % { $_ -Replace '(https://web.archive.org/nebula/level)([0123456789]{2})/', 'Level$2.html' } | Set-Content $item

I needed this once when I was trying to refresh the Library share. It failed on refresh with an error saying that a DVD was in use and wouldn't refresh until it was no longer in use. The following commands allowed me to identify the machines.

In general all of these need:

{{{#!highlight powershell
Import-Module VirtualMachineManager
}}}

== Get a list of Virtual Machines that have a DVD attached ==

{{{#!highlight powershell
