    I have a wireless adaptor but i didn't change its mac address on windows 7.

    I can change it on vista or xp but not windows 7

    I used these (smac,tmac,amac, and registry,.. etc) but it cant change

    How can i change it?

    Follow these steps:

    Network and Sharing Center > Change adapter settings > right click on adapter name, then Properties > Configure > Advanced tab > Network adress

    By default, "Not present" value it's on. Just click on the blank field and write the MAC address you want (without the lines, eg. 00FB0R...).

    Make sure the two starting values are different from the original (i.e. if it is 00, change it to 12 or A5 or something).

    Now open regedit and do the following :

    Navigate to :

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318]

    Under this key, you shoud see numbers in sequence as “0000″, “0001″ and so on. Click on one at a time to check the description of the device to match it with the mac of your Network Card. In my case (0001)

    Once found, in the right-pane, look for “NetworkAddress” key value. If you find it, right-click and select modify. Enter the desired MAC-Address as a 12 digit number (all in one, no “space” “.” or “-”)

    If you don’t find the key, right-click in the rightpane, select “New” – “String Value”. Enter the name as “NetworkAddress”. Now modify and set the desired value

    Now, disable and enable the Network card from the ControlPanel – Network Connections.

    This should reflect the new MAC-Address on your NIC. Should you choose to go back to the original manufacturer set MAC-Address simply delete the key you just created/modified in the Windows Registry.

    if you are using intel pro wireless ard you should use old driver for it. i think it version must be 11. etc.. if you use newer version for this card you can not change mac adress (include xp)

    I followed the steps I gave you in previous post, to test myself.

    Here's the result :

    Before :

    After applying in device maanger and registry :

    after.jpg


    I confirmed it by leaving mac-filtering ON in my router. It wouldn't connect.
    So I then added the new mac address in the mac-filter list, and I got a connection again.


    So it should work. Maybe try again ?

    Yes it does. I changed my mac that way and it has stuck after 100's of reboots and connects/disconnects to wireless access points.
