To determine your hardware address:
Windows 8 & Windows 10
1. Press the Windows key to open the Start screen.
2. From the Windows Start screen, begin by typing cmd.
3. Windows search will filter the available apps until Command Prompt is displayed, select this app and the black Command Prompt window will open on the desktop.
4. In Command Prompt, type ipconfig /all and hit Enter (note the space before the forward-slash).
5. In the results, you may need to scroll up to view the appropriate addresses for your computer’s adapters. The hardware and IP addresses will be listed as Physical Address and IPv4 Address, respectively. There may be more than one (if your computer has both a wired and wireless way to connect to the internet, for instance). In that case, if the addresses are listed under a 'WiFi' heading, then they are for wireless, and if they're under 'Ethernet' then they're for wired.
1. Click the Windows Start button (the Windows button in the lower left corner of your screen). Type cmd in the "Start Search" field and hit enter.
2. At the C:\ command prompt, type getmac /v. Your network adapters will be displayed, including the twelve-digit physical address for the Local Area Connection, which is your Ethernet adapter's address.
If you have a wireless network adapter and wish to use it, the physical address for the wireless network adapter is also displayed. You can tell the wireless apart from the wired hardware address by a "Wireless" or "802.11" label in either the "Connection Name" or "Network Adapter" fields. You will need to enter these numbers (without punctuation) into the automated registration system. If it says "Wireless Disabled", please enable your wireless adapter (often a switch on the outside of a laptop case or a key combination) and run getmac /v again.
3. When you have finished viewing the hardware addresses, type exit at the C:\ prompt to close the window.
