Before cloning a VM, you may want to prepare the source VM with the Sysprep utility to reset and remove the unique security identifier (SID) for the VM, and avoid issues such as two computers have a same IP address or two computers have the same computer
name. This step is recommended for VM that is joined to Active Directory (AD) domain on the same network, but is not required most of the time, and can usually be skipped for virtual machines running as workstation. Once its done, right click the existing
VM in Hyper-V manager console and select ‘Export’. Specify the location where you want to save the exported VM. You can click on Browse button to select a folder. Avoid choosing the same location as the .vhd file (virtual hard disk file) for the existing VM.

a unique ID for the cloned VM
