1. At a command prompt, type:
netsh interface ipv4 show interfaces
2. Verify that there is an interface list. At a command prompt, type
C:\netsh interface ipv4 set address name=<ID from interface list> source=static address=<preferred IP address> gateway=<gateway address> mask=<mask address>
3. Verify by typing ipconfig /all at a command prompt and checking that DHCP enabled is set to No.
netsh interface ipv4 set address name=12 source=static address=10.0.0.11 gateway=10.0.0.10 mask=255.255.255.0
This also works on a Windows 8 install.
