Issue: When installed Deep Freeze does not properly freeze a Hyper-V virtual machine running a Generation 2 virtual disk.

To determine if your virtual machines are running as a Generation 1 or a Generation 2 machine run the following command in Power Shell;

Get-VM | Format-List Name,Generation

The output will list your virtual machines showing output similar to the following indicating the generation of the virtual machine.

Name       : server-01

Generation : 1

Name       : server-02

Generation : 2

This issue stems from changes made in the configuration of the Generation 2 Hyper-V virtual machines. Currently Faronics recommends using a Generation 1 virtual machine for applications where Deep Freeze needs to be installed on a Hyper-V Virtual Machine.
