  1. Changing IP Address in Windows 10 triggers a deactivated digital entitlement or registration - Windows 10 deactivates itself. Tried it on 5 computers and they all deactivated within 5-10 minutes of being online and could not activate again until I restore an image.

    1. Is it really IP address or MAC address? Can you post some screenshots? Is the Windows licence OEM or retail?

    1. Try it again by unchecking the "automatically restart network connection to apply changes", and then manually disable and enable the wifi network adapter from network connections/device manager.

    2. The same issue here. I've tried your suggestion. But still no luck.
      By the time i can change the mac address, the description of new installed mac address is missing.

    1. This error is triggered only when TMAC.exe has been tampered/modified/corrupted. If you are getting same error even after reinstalling TMAC then there is a good chance of your PC being infected with a malware. Certain malware infect other software executable and in such case when TMAC.exe gets modified, TMAC will throw this error message and exit.

      Delete
    2. so,this error can't fixed?

      Delete
    3. Since the error keeps coming even after reinstall, it means something is modifying the TMAC.exe and you should get your PC checked for malware.

    1. Depends on your network type & configuration. Check what IP address you are getting.

  11. What do you mean? It is a wireless. I have tried multiple IP addresses, including merely changing a single number but I still cant get on. I have an intel and windows 7.

    1. Are you connecting to a access point which you have setup at home or are you directly accessing wifi provided by your ISP?

    2. I connect to the access point/ router the way I always do. As soon as I change mac, I get disconnected, I click on access and it waits a bit then says 'cant connect'; as soon as I switch back I connect again without clicking anything.

    3. Email screenshot of TMAC with the wifi adapter selected. Also take screenshot of the IP Address tab in TMAC. Send those screenshots to support@technitium.com.

    1. You need to either use full path to the exe file or change directory to the directory in which the exe is installed. By default, the installation directory should be "C:\Program Files (x86)\Technitium\TMACv6.0".

    1. It may be that some component needed by TMAC is not installed correctly. You can try steps given in this blog post to see if that fixes the issue.

  20. how can we manually update oui.txt sometimes it gives error when trying to update, where is this file located on computer (windows) so we can copy and paste from website and save to a file named oui.txt thenn copy to the directory to update previous file ?

    thanks

    ReplyDelete

    1. The oui.txt file is not used as-is. It is downloaded and converted into a binary formatted file oui.db which is stored in the location where TMAC is installed. There is no option to manually provide OUI.TXT but, you could setup local web server, add an entry to "hosts" file for standards-oui.ieee.org and force the software to download it from your local web server.

  21. Shreyas: Are you aware that Windows 10 now offers a network setting for some wireless adapters "Random Hardware Address"? Also, when connected to a wireless network you can click on the name of the network in the Win 10 Network Settings and an additional option is presented where you can set the network to randomize hardware address every 24 hours for that network. This is not offered for all wi-fi adapters but it is offered for the Intel 7265 ac adapter in my Lenovo laptop. I noticed that this built-in feature always changes the 2nd digit of the first octet to either a 2, 6, A or E. Apparently Windows will not accepted any other hex number in that position.

    1. Yes, I am aware of the Windows 10 feature for wireless ethernet adapters. The 2nd digit of the first octet can be 2, 6, A or E due to the fact that when you converted it to binary, you will notice that the second bit is set, which notifies that the MAC address is locally administered.

    2. Hi,

      On my laptop (Win7) problem: MAC address is changed after every reboot. The reason is suing over the hardware problem. I tried to use TMAC, something to change the MAC address, it has been successfully changed, but after rebooting the laptop, he changed again. Perhaps with the help of TMAC solve my problem, is to establish a permanent MAC address?
      I send a screenshot of the TMAC window to support@technitium.com.

  23. The TMAC utility just worked fine yesterday and this very morning. Then after applying some automatic MS updates it is saying

    "Failed to change MAC Address. For Wireless Network Connections, set the first octet of MAC address as '02' and try again"

    I removed the latest updates for MS .NET Framework 4.6.1 (KB3205402) and Windows (KB3197869, KB3207752 and KB3210131).
    I uninstalled TMAC, restarted Windows 7 and reinstalled TMAC.

    Still I can't get my MAC address changed on the wify port.

    Replies
    1. TMAC does not have any .NET dependency. The reason mostly could be that Windows Update installed new network adapter drivers. You can try installing older version that you may have with the drivers DVD.

  26. Lately I have noticed that when changing MAC address a few times during computer session (Windows 10), your latest version unexpectedly crashes during one of the latter changes. It first shows the regular "Changing MAC address..." message and then freezes. (Program not responding in the Windows dialog message). At this point two windows of the program exist: The regular one showing it is still trying to change an address, and the blank one which cannot be even focused on. The Ctrl+Alt+Delete or even reset do not work. The only fix is to completely shut down power and then restart the computer.

    1. The usual problem when TMAC gets stuck is with disabling/enabling the network adapter to apply the changes. It may be issue with driver or file corruption. You could try unchecking the "Automatically restart network connection to apply changes" and after changing the MAC address try enabling/disabling network adapter manually from Network Connections or Device Manager. It may happen that the network adapter gets stuck even when you try doing it manually.
