Just updated 2 computers to 16273 and have the same problems again: many Settings are back to their Default's! Also, the fixed IP's of those computers are changed to default DHCP (not fixed IP) and LAN resettled to an IP used in the DHCP area (above 192.168.1.100), while all my fixed IP's are below 192.168.1.100! By no. 3 (Laptop) will be the same after finishing, it's working on the update right now!
