An ISO is mounted when you install the Hyper-V Integration Tools … but not unmounted when the installation is finished. So whenever I go to a customer for migrations or maintenance on a Hyper-V (SCVMM) environment, I always dismount those ISO’s.

Doing this manually takes a lot of time and is a task that kinda sucks… So, let’s use my favorite tool for that: PowerShell.

The following script will dismount all ISO images:

Get-VirtualDVDDrive -VMMServer $VMMServer -All | Where-object {($_.ISO -ne $null) -and ($_.ISOLinked -eq $false)} | Set-VirtualDVDDrive –NoMedia

But what if you would only like to dismount the Hyper-V Integration Tools ISO and leave the rest intact?

Get-VirtualDVDDrive -VMMServer $VMMServer -All | Where-object {($_.ISO -ne $null) -and ($_.ISOLinked -eq $false) -and ($_.ISO -like ‘vmguest’)} | Set-VirtualDVDDrive -NoMedia
