to change you MAC address go to control panel, system, hardware, device manager, and find your network card (the one you use internet for write down complete name)
go to registry and use a search to find your network card by full name.
When you find it in that same folder add string and call it "NetworkAddress" all one word, open the string and write your NEW MAC address
12 letters and numbers in total together no "-" just letters and numbers together,
