Before diving into the error's root cause, it’s helpful to know the standard ways to change a MAC address. Windows provides a few built-in methods:
Many home routers have a feature known as "MAC Address Clone". This tool allows you to set the router's outward-facing MAC address to any value you choose. After logging into your router's administration panel, look for a "MAC Address Clone" or "MAC Address Spoofing" section, typically under the "Advanced" or "Network" settings. By setting your router to use your desired MAC address, all traffic leaving your home network will appear to originate from that address.
that trigger the error:
"Failed to change MAC address for wireless network connection set the first octet work"

If you try to set a MAC whose first octet is, for example, 01 (multicast) or 00 (globally unique with LAA=0), some drivers will refuse or silently ignore the change. After logging into your router's administration panel, look
ipconfig /all
