First in a powershell create a new network switch

New-VMSwitch -SwitchName "Hyper-V [VM NAT]" -SwitchType Internal
Get-NetAdapter       // (note down ifIndex of the newly created switch as INDEX)
New-NetIPAddress -IPAddress 192.168.0.1 -PrefixLength 24 -InterfaceIndex <INDEX>
New-NetNat -Name HyperV-NATnetwork -InternalIPInterfaceAddressPrefix 192.168.0.0/24

In your ubuntu server open your network netplan

Nice ansible playbook and supplemental Makefile for bulk change of default username on raspberry pi running on raspbian distribution. It can be easily modified for mass changing passwords on any templated virtual machines or devices. For use just run: make rename_pi_user i=10.0.0.1,10.0.0.2,10.0.3

# 1. Place this file to /etc/grub.d/05_Windows
# 2. Update Windows patrtition setting. In this example Winodws will be booted from hd0,1 - sda2 partition ("hd0" is sda, and ",1" is second partition on disk)
# 3. Add "GRUB_DEFAULT=saved" and "GRUB_SAVEDEFAULT=true" lines to /etc/default/grub for save last booted OS
# 4. Run "chmod +x /etc/grub.d/41_Windows && grub2-mkconfig --output=/boot/grub2/grub.cfg" after all modifications for make new config file
exec tail -n 5 $0
