Q. How can I un-cluster a Hyper-V virtual machine (VM)?

A. If you made a VM highly available using failover clustering and now you want to make it a standalone VM again, the easiest way I've found is to export the VM to the desired location. Delete the virtual machine as a resource group from failover clustering, delete the VM from the Hyper-V snap-in, then import it back in.

Because you already exported the VM to the desired final location, there's no need to duplicate the files again when you perform the import. Select the Move or restore the virtual machine (use the existing unique ID) option and don't check the Duplicate all files so the same virtual machine can be imported again, as shown here.
