Check Hyper-V Integration Services Versions

Ensuring that all your hosts have Integration Services Installed and are all the same version is important to keep your Hyper-V environment in a optimal/stable state.

I use the following PowerShell command to list all VM's and associated Integration Services version on a Hyper-V host:
Get-VM | ft Name, IntegrationServicesVersion

I use the following PowerShell command to list all VM's and associated Integration Services version on a entire cluster:
Get-ClusterGroup | Get-VM | ft Name, IntegrationServicesVersion
