    Windows 10 changing MAC Address and remove Machine GUID

    I have couple of questions here, Does changing your mac address, removing machine GUID, and changing the hostname harm to your computer ?

    No, it does not harm the computer but quite possibly will harm connections, networking, things you want to do with the equipment you have. What is the need for changing?

    Changing mac address can stop the network working if you get it wrong

    Mac addresses are assigned to networking devices by the manufacturers because each of them have a set of addresses they can use.

    If your PC has both wired and wireless networking, it will actually have two Mac addresses - one for each device.

    You really should not be changing them, and if you are "spoofing" addresses (i.e., providing a fake address), that could be considered illegal activity in some contexts and should be avoided.

    I need to change it because i've been banned from an online games for no reason and the admin advice me to do this step:
    1. Change MAC address with TMAC
    2. Change the hostname in regedit
    3. Removing random number in HKEY_CURRENT_USER\SOFTWARE\Microsoft\xxxx and last one
    4. Removing machine GUID in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography
    That's step i need to do, to get unbanned. But i afraid all of step above could harm my computer because of changing registry.

    Usually the worst thing that happens when futzing around in the Registry is a wrong entry can prevent booting up, results in reinstalling Windows. I always make a new System Restore point before working in the Registry. Or one can use Registry menu options to Export a copy of the Registry, click on the topmost item on the list in the left column first.
