Follow these steps to apply the change correctly through the Windows Device Manager :
When you try to manually assign a MAC address, you aren't just typing a random string of numbers and letters. A MAC address carries metadata within it. Specifically, the first half of the address (the first three octets, or the first 6 characters) identifies the manufacturer. Follow these steps to apply the change correctly
When attempting to spoof or change a wireless MAC address on Windows using tools like Technitium MAC Address Changer (TMAC) , users often encounter an error message stating: . When attempting to spoof or change a wireless
Changing a network interface’s Media Access Control (MAC) address—known as spoofing or cloning—is a common practice for privacy, network testing, or bypassing access controls. On a wired Ethernet connection, most operating systems allow arbitrary hexadecimal values. However, on wireless network interfaces, users often encounter a frustrating failure: they can change the last five octets (e.g., XX:XX:XX ), but any attempt to modify the first octet (e.g., changing 2C:54:91:... to 00:11:32:... ) results in an error, a reset to the original, or a non-functional connection. This essay examines why the first octet fails and outlines the limited practical workarounds available. separated by colons or hyphens.

A MAC address is 6 bytes (48 bits). The first byte contains two special single-bit flags (bits numbered from least significant bit (LSB) upward in each byte):
A MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communication at the data link layer of a network segment. It's usually represented as six groups of two hexadecimal digits, separated by colons or hyphens.
