You can use the Get-VM command to determine the Integration Services (IC) version number of the virtual machines running on your Hyper-V host:
Get-VM | Format-Table Name, IntegrationServicesVersion
The resulting IC version numbers include the build number of the Windows Server operating system as follows:
6001 – Windows Server 2008
7600 – Windows Server 2008 R2
7601 – Windows Server 2008 R2 SP1
9200 – Windows Server 2012
9600 – Windows Server 2012 R2
From the above we can see that the guest OS of this VM is Windows Server 2012.
