Set DHCP Client ID on Windows 7 Ultimate

Hi, I am running windows 7 64-bit on BootCamp on macbook pro 13-inch (late 2012). On Mac OSX I could set up a custom DHCP client ID on the DHCP settings of my Wi-FI. How could i do this on Windows? Without this, My hotel public Wi-Fi would not redirect me to their authentication page at all (which is important, because I a m staying in this hotel for a long while...) View image: dhcp...
