Soo, basically I have got a reason to change my MAC address and every time I do it in the registry or here:
http://prntscr.com/hlhnz9 and then I check in TMAC and it says the address is inactive. http://prntscr.com/hlho2g
I can also add I have a Huawei router that's connected to the pc with a mini usb to usb cable, and it is recognised as
Remote NDIS Based Internet Sharing device #2.
I've run out of things to try.
Sorry but with a corrupted HDD and well, this could be caused by that. There's a second problem is that it appears you are using virtual devices rather than a real Ethernet NIC or WiFi connection. While I know a bit about networking as I wrote router code in the 90s what you have looks very non-standard. Plus changing your MAC address on the PC won't affect what happens on the Internet link so without a lot more story and links to products so I can see if they document the feature I have to wait till there's more info. This doesn't mean it can be done.
Why not a standard setup?
EDIT: Also there is nothing else than this : http://prntscr.com/hlhovx In the sharing device.
The best way to change a MAC is to use other hardware. Just buy and install a PCI Ethernet card and you're done.
On the TMAC screen in https://technitium.com/tmac/ I see a checkbox to make the changed MAC persistent. If that doesn't work, contact their tech support.
