Here are the steps to change the MAC address on most NIC cards. Remember to save your current MAC address as some ISPs authorize your MAC address and its possible that by changing your MAC address you may not be able to get back onto the internet, so you'd need to change it back.
Go to Start->Control Panel and double click on Network and Internet Connections
Click on Network Connections
Right click on the NIC you want to change the MAC address and click on properties.
Under “General” tab, click on the “Configure” button
Click on “Advanced” tab
Under “Property section”, you should see an item called “Network Address” or "Locally Administered Address", click on it.
On the right side, under “Value”, type in the New MAC address you want to assign to your NIC. Usually this value is entered without the “-“ between the MAC address numbers.
Goto command prompt and type in “ipconfig /all” or “net config rdr” to verify the changes. If the changes are not materialized, then use the second method.
If successful, reboot your systems.
Doesn't seem to work the same on wireless NICs
