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
Get-SCVMMServer -ComputerName Samuel
Get-SCVirtualMachine | Get-SCVirtualDVDDrive | Where-Object {$_.Connection -eq "ISOImage"} | Select Name, Connection, ISO
}}}

== List VMs at the end of the semester to be deleted ==

{{{#!highlight powershell
Get-SCVirtualMachine | Select Name, MarkedAsTemplate, Owner | Sort-Object -Property Owner, Name | Export-Csv -Path .\vms2019w.csv
}}}

For the uninitiated:

Symbol

Meaning

%

shortcut for foreach object

$_

current object in the pipeline

Get-Member

Will list the fields of the object you send it

Sort-Object -Property [property name]

Will sort the objects you send in by the property name(s) which can be a comma separated list

Windows and AD Scripts

List of AD accounts and the last time they logged in

   1 Get-ADUser -Filter * -SearchBase "dc=home,dc=scotnpatti,dc=com" -ResultPageSize 0 -Prop CN,samaccountname,lastLogonTimestamp | 
   2      select CN, samaccountname,@{n="lastLogonDate";e={[datetime]::FromFileTime($_.LastLogonTimestamp)}}

List Memory Installed

   1 Get-WmiObject win32_physicalmemory | Format-Table Manufacturer,Banklabel,Configuredclockspeed,Devicelocator,Capacity,Serialnumber -autosize

List object from Registry - namely version of .NET installed

   1 gci 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' | sort pschildname -des | foreach-object {$_.name; $_.GetValue("Version");}

Remote commands

   1 Invoke-Command -ComputerName eve -ScriptBlock { date }

Replace a string in a file using a regular expression

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. 

   1 $files = ls Level*.html
   2 foreach ($item in $files) {
   3     (Get-Content -path $item) | % { $_ -Replace '(https://web.archive.org/nebula/level)([0123456789]{2})/', 'Level$2.html' } | Set-Content $item
   4 }
