MAC or “Media Access Control” Address is hardware address assigned to network interface devices. So, your laptop, smartphone, WiFi radio, each of them have a separate and fixed MAC address. While connecting your device to a network (e.g., WiFi Hotspot), your MAC address is recorded there. The owner can’t directly identify if it’s your device but he can see it’s MAC address and block it if he finds it annoying.
Normal users can’t directly change it on their will so it works fine. But if you know how to “spoof” or “change” your device’s MAC address then even after blocking your MAC address, you can still connect your device to your desired network by changing your mac address. Not only this, you can enjoy few more benefits as mentioned below –
Then go to the Hardware tab; you will see the MAC Address there. How to change your MAC address on a Mac OS X. To change your Mac Address on a MAC OS X.

And, Yes! It’s legal. MAC address assigned in a factory and it’s legal to change your device’s MAC address.
So here in this article, we are going to show how to change or spoof MAC address in your Windows Operating System. Although, we are providing this guide through our Windows 10 OS but steps are similar for Windows 8.1, 8 and 7 OS. https://glcgbmr.weebly.com/blog/send-app-notification-macos. Scroll down to know how to change MAC address in Windows 10.
List All Network Adapters with their MAC Address
Before changing MAC address of your PC, you first need to check if there are more than one network interface hardware in your device as each of them have different MAC address and you need to change only that using which you connects to a network.
So, open command prompt either by typing “command prompt” or “cmd” at Cortana bar or Windows search bar or by opening RUN dialog box by pressing Win+R and typing “cmd” in there and hit ENTER!
Now in the command prompt window type –
cd

To verify if you have successfully spoofed your MAC address, you can run command prompt commands mentioned above to check if your network adapter’s MAC address spoofed or not.
When Apple announced its devices would use random MAC addresses when searching for Wi-Fi networks, it received extensive media attention. And rightly so. It prevents companies from tracking your movements, and Apple was the first major player to start doing this. Windows and Android are quietly trying to catch up. As a result, some devices running Windows now support MAC address randomization, and we will discuss how it's implemented, and where it fails. This information is a small selection from the recent paper Why MAC Address Randomization is not Enough: An Analysis of Wi-Fi Network Discovery Mechanisms.
Update: we have contacted Microsoft, and they are in the process of addressing the vulnerabilities we discovered. How it works
Microsoft first added support for MAC address randomization in Windows 10. Unfortunately, it's only available if you have a WiFi card and driver that support it. For example, the Intel 7265 AC, when using the latest driver, supports randomization [1]. You can see if your hardware supports MAC address randomization by going through the following menus:
As you can see, I have it enabled on my laptop. So far it's been working quite well. What's very interesting about Microsoft's approach is that it also uses random MAC addresses when connecting to a wireless networks. In contrast, Apple only uses random addresses when searching for nearby networks, and it falls back to its original address when connecting to a network. In this aspect Windows 10 offers better privacy than Apple. Using a random MAC address to connect to a network can cause problems if users are authenticated (i.e., recognized) based on their MAC address [2]. Interestingly, Windows avoids this issue by always using the same random address every time it connect to a specific network. For example, let's say you want to pay for Wi-Fi access, and they authenticate you based on your MAC address. Then this is not a problem. The first time you connect, Windows will generate a random MAC address. And if you reconnect to this network at a later point in time, Windows will reuse the previously generated address. Therefore the system can still recognize you, and you don't have to pay twice. There's one downside to this approach: since you always use the same address when connecting to a particular network, an adversary can learn when certain devices connect to specific networks. Nevertheless, compared to the old situation where you'd always use the original MAC address, it improves your privacy. Technically, the random MAC address that is used to connect to a network is calculated as [5]: address = SHA-256(SSID, real MAC address, connectionId, secret)[:6]Here SSID is the name of the network you are connecting to, real MAC address the original address of your network interface, and How To Change Your Mac AddressconnectionId is a value that changes every time the user removes (and re-adds) the network (i.e., this value is updated if you 'forget' the network under Windows 10). The secret parameter is a 256-bit cryptographic random number, generated during system initialization, and kept the same across reboots. Every interface has a different value of theHow To Change Mac To Windowssecret parameter, to assure each interface gets different random MAC address. Finally, bits in the most significant byte of addressIt's also possible to disable randomization for certain networks. In this case Windows will use the original address when connecting to a network. You can configure this through the following settings when you are currently connected to the network: Notice that the user has three options for each specific network:
Remark that if randomization is enabled, independent of the above options, Windows 10 will always use random MAC addresses when scanning for nearby networks. This 'scanning' address changes every time you connect (and disconnect) from a network, and when you restart your device [3]. Hence it doesn't change that frequently, but it's still sufficient to prevent tracking over extended periods of time. In contrast, Apple changes the scanning address roughly every few minutes, which provides more privacy.
Basic Security Analysis Randomization as implemented in Windows 10 significantly improves your privacy. So enable it! Unfortunately, it's not perfect, because there are still some ways to defeat or bypass it. The first weakness is that the sequence number contained in WiFi frames is not reset when changing the (random) MAC address. This sequence number, which is present in most Wi-Fi frames, is used to detected retransmissions, and is incremented by one after successfully transmitting a frame. As shown in the picture below, when the MAC address changes because the user connects to a network, the sequence counter is not reset: The last frame from ea:69:0a:* has the sequence number of 92, and the other address 7c:5c:f8:* has the sequence number 94. Based on this an adversary can reasonably conclude that both frames are sent by the same device. In other words, he learns that the same device was using both addresses, defeating the purpose of address randomization. The second problem is that Windows 10 reveals its real MAC address when interacting with Hotspot 2.0 networks. But what's Hotspot 2.0? Simply put, Hotspot 2.0 is a new standard to automatically and securely roam between WiFi networks. No manual interaction is needed. Your device automatically determines whether you have the appropriate credentials (passwords) to connect to a network. Think of this like the cellular network: when you get off the plane, your phone automatically finds and connects to a foreign cellular network. Hotspot 2.0 provides a similar experience for WiFi. In order to accomplish automatic roaming, Hotspot 2.0 sends ANQP queries to the Access Point before connecting to it. These ANQP queries request detailed information about the wireless network. This information includes the credentials that are needed to connect with the hotspot, whether the hotspot provides internet access or only local network access, etc. Unfortunately, Windows 10 sends these ANQP queries using the real (original) MAC address: In the first probe request it uses the random MAC address 2a:b3:e6:*. These probe requests are used to detect the presence of networks. If there's a Hotspot 2.0 network nearby, Windows will send ANQP requests using the real MAC address, in this case 7c:5c:f8:*. Therefore an attacker can obtain your real MAC address by advertising a Hotspot 2.0 network. Thankfully, Windows 10 only sends ANQP queries if at least one Hotspot 2.0 is configured. Since this standard is not yet widely deployed, few users will have such a network configured [4]. Detailed Security Analysis Want to know all flaws that are present in existing implementations of MAC address randomization? And this specifically for Android, Apple, Linux, and Windows? Then read my paper Why MAC Address Randomization is not Enough: An Analysis of Wi-Fi Network Discovery Mechanisms [5]! It has everything explained in technical detail. References and Footnotes [1] If you have an Intel 7260 AC, you can also force Windows 10 to use the drivers of the Intel 7265 AC. Your device will still work, and will support MAC address randomization. [2] Even though authentication based on the MAC address is utterly insecure (an adversary can easily spoof a MAC address), it's still used by many systems. [3] C. Huitema. Personal communication, Nov. 2015. [4] One notable exception is the Passpoint configuration provided by Boingo. Essentially Passpoint is a synonym of Hotspot 2.0. If you have this configuration installed, you have a Hotspot 2.0 capable device, and the Boingo configuration will use Hotspot 2.0. This means Windows will send ANQP queries to nearby Hotspot 2.0 networks. [5] M. Vanhoef, C. Matte, M. Cunche, L. S. Cardoso, and F. Piessens.
