If you install Windows 10 on a HP Microserver you might find that the Network Ethernet Port cannot be accessed by the OS.
The solution might be a BIOS update using firmware upgrade SP64420.exe download. Version 2013.10.01 (A) (15 Nov 2013) can be found here.
After creating the Update USB and booting to it the update finished untidily at a command line prompt – but was successful.
