Question: What does a magic packet do in Windows, is it a security concern ?

Answer: When you turn your computer off the LAN adapter still has power so that it can tell the computer to turn on if it receives a so called 'Magic Packet'. The "magic packet" is any broadcast packet where somewhere in the data payload of the packet, there are six bytes' worth of all ones. That is to say, FFFFFFFFFFFF, six bytes of all ones, followed by 16 repetitions of the MAC address of the NIC whose computer you want to wake up. This is not a security concern but you can turn it off.
