In case anyone else stumbles upon this, don't forget to set your Hyper-V VM to actually use Enhanced Session Mode:

Set-VM -VMName <your_vm_name> -EnhancedSessionTransportType HvSocket

This worked perfectly on the 2019.1 release of Kali.

Thanks, works great with Kali 2019.1, you have to run the script 2 times (two reboots) and then use the command provided by @jsorah
