2012 R2 Hyper-v VM delete empty VM disk to free space for the host?

I have a VM that has a 1.5TB empty disk volume that I want to remove and have the space go back to the physical host.

I think the correct steps would be to first use Disk Management in the VM to Delete Volume and then Hyper-V Manager to remove it from the VM itself.  

Can anyone confirm these steps?

Thanks!
