[Optional] Update Port Reservation

As for Sept 2020, Hyper-V has a way of dynamically reserving thousands of ports that are normally used by different apps (sub-10K range). This sometimes make apps failed after a restart due to reservations. To fix this problem, we will move its reservation to 40K+ range.

### Show what ports are being reserved
netsh int ipv4 show excludedportrange protocol=tcp

netsh int ipv6 show excludedportrange protocol=tcp

### Change the range for dynamic ports
netsh int ipv4 set dynamic tcp start=49152 num=16384

netsh int ipv6 set dynamic tcp start=49152 num=16384

### Prevent port reservation
reg add HKLM\SYSTEM\CurrentControlSet\Services\hns\State /v EnableExcludedPortRange /d 0 /f
