How to configure preferred static IP on Windows 10?

There should be areas in the DHCP/Autoconfiguration config of Windows Server 2008 that defines the preferred IP address(es) for a certain MAC address. Find the MAC address of your PC in question (in this case, 78-AC-C0-BF-31-54), and search for that MAC in the DHCP leases. You should be able to change the preferred IP in that section. If you have subnets setup, you'll need to look in that specific subnet for the PC. If you want to change the IP to an IP that belongs in a different subnet, you'll need to move the PC to said subnet. Take a look at this documentation for some more information about the whole deal.
