Did you ever need to change your MAC address?
Suppose you want to connect to a network, where there already a PC having same MAC address has been connected. So you may not be able to connect because of MAC Address conflict within the same router.
In this case you may need to change your MAC Address.
Its pretty cool in windows just but to change a win registry item.
>open registry using regedt32
>open item HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\
>Under this key you will find a bunch of sub keys labeled as 0000, 00001, 0002 and so forth. you can assume any MAC address you want by finding the key that controls the NIC we want to change, putting in a string value called “NetworkAddress” and setting it to the MAC address you want to use formatted as a twelve digit hex number.
>done. Just restart your network connection...cool...
