If you are using Windows Vista, Windows 7 or higher, you have to go to Control Panel, then Network and Internet, then Network and Sharing Center, and then click on Manage Network Connections or Change adapter settings. It will normally either be Local Area Connection or Wireless Network Connection. Step 1: Click on Start, then Control Panel, then Network Connections, and right-click on the network connection you want to change the MAC address for and select Properties. You can change the MAC address for the network card in Windows pretty easily following the steps below. If you have more computers that need to connect, you can spoof the MAC address of an authorized computer and connect from a different computer.
Another example is if you have an ISP that allows only a certain number of computers to connect to the Internet from your home.
