:counterclockwise_arrows_button: MAC Address Changers on Windows 10 & 11 — Stop Broadcasting Your Identity

Every network adapter on your PC has a unique fingerprint. It’s called a MAC address. And right now, every Wi-Fi hotspot, router, and network admin you’ve ever connected to has seen yours.

Changing it takes less than 30 seconds — if you have the right tool.

:world_map: Why Your MAC Address Is a Privacy Problem

Your MAC address is a 12-character code burned into every network adapter at the factory. Think of it as a serial number for your Wi-Fi card or Ethernet port. Every time you connect to any network, that code gets broadcast.

Who sees it:

  • Every Wi-Fi hotspot you’ve ever joined (airports, cafes, hotels, malls)
  • Your ISP’s router
  • Any network admin on the same LAN
  • Tracking systems in public spaces (yes — shopping malls and airports use MAC tracking to monitor foot traffic)

What they can do with it:

  • Track your device across different visits to the same location
  • Build a movement profile based on where your MAC shows up
  • Fingerprint your machine even if you change your IP
  • Identify your device manufacturer and narrow down what hardware you’re running

Changing your MAC = cutting that tracking chain. Your adapter still works perfectly — it just introduces itself with a different name every time.

100% legal. Standard privacy practice. Every major OS now has some form of MAC randomization built in because even Microsoft and Apple admit it’s a problem.

:high_voltage: The Tools — Ranked by Ease of Use

🏆 1. Technitium MAC Address Changer (TMAC) — The OG King

The most popular MAC changer on Windows. Period. Free, lightweight, been around forever, and still works flawlessly on Windows 10 & 11. If you want one tool that just does the job — this is it.

What makes it the go-to:

  • One-click random MAC generation
  • Works on Wi-Fi, Ethernet, and Bluetooth adapters
  • Set a specific MAC address manually or let it randomize
  • Restore your original MAC with one click
  • Save presets — switch between different MAC configs instantly
  • Full command-line support for automation and batch scripts
  • Updates vendor database from IEEE.org (so generated MACs look legit)
  • Shows detailed adapter info: IPv4, IPv6, speed, driver version, manufacturer

How to use it (30 seconds):

  1. Download from https://technitium.com/tmac/
  2. Install — no bloatware, no bundled garbage
  3. Launch TMAC (run as admin)
  4. Select your network adapter from the list (Wi-Fi or Ethernet)
  5. Click “Random MAC Address” — or type a specific one
  6. Hit “Change Now!”
  7. Done. Adapter restarts with the new MAC in about 2 seconds.

To go back to your real MAC:
Click “Restore Original” — instant.

Pro move — presets:
If you regularly switch between networks (home, office, public Wi-Fi), save a preset for each. One click to swap your entire network config — MAC, IP settings, DNS, everything.

Pro move — command line:
Automate MAC changes with batch scripts. Set your MAC to randomize every time you boot, or every time you connect to a new network. TMAC’s full functionality is accessible via CLI.

How it works under the hood:

It writes a single registry value:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
{4D36E972-E325-11CE-BFC1-08002bE10318}\[NIC ID]\NetworkAddress

When Windows sees that value, it uses it instead of the hardware MAC. Remove it → Windows falls back to the real one. Clean and reversible.

🪟 2. Windows Built-In Random MAC (Zero Install)

Didn’t know this existed? Most people don’t. Windows 10 and 11 have MAC randomization built right into the settings. No download needed.

The catch: Wi-Fi only. Doesn’t work on Ethernet. And you can’t set a specific MAC — only random ones.

Enable for ALL Wi-Fi networks:

  1. Open Settings → Network & Internet → Wi-Fi
  2. Toggle “Random hardware addresses” → ON
  3. Done. Windows generates a random MAC every time you connect.

Enable for a SPECIFIC network:

  1. Settings → Network & Internet → Wi-Fi
  2. Click Properties on your connected network
  3. Under “Random hardware addresses” choose:
    • On — new random MAC every connection
    • Change daily — fresh MAC every 24 hours
    • Off — use your real MAC (default)

When to use this vs Technitium:

Situation Use Windows Built-In Use TMAC
Quick public Wi-Fi privacy :white_check_mark: :white_check_mark:
Ethernet adapter :cross_mark: Can’t :white_check_mark:
Need a specific MAC :cross_mark: Random only :white_check_mark:
Bluetooth adapter :cross_mark: :white_check_mark:
Automation / scripts :cross_mark: :white_check_mark: CLI
Persist across reboots :white_check_mark: Stays on :warning: Reapply
Zero install :white_check_mark: :cross_mark: Needs install

If the option is grayed out or missing: Your wireless adapter doesn’t support it at the hardware level. Older adapters or certain budget models don’t have the feature. Use TMAC instead.

No download needed — already on your PC.

🛡️ 3. NoVirusThanks MAC Address Changer — Lightweight & Dead Simple

If Technitium feels like too much software for the task, this is the stripped-down alternative. Bare minimum UI. Does exactly one thing.

What it does:

  • Lists all physical and virtual network adapters
  • Shows current MAC, manufacturer, connection type
  • One-click random MAC generation
  • Manual MAC entry
  • Restore original with one button
  • No .NET Framework required
  • Works on Windows 7 through 11

How to use it:

  1. Download from https://www.appsvoid.com/products/mac-address-changer/
  2. Install (tiny — no bloat)
  3. Select adapter → Click “Change MAC”
  4. Enter new MAC or click “Generate Random”
  5. Click “Change” → done

Why pick this over TMAC:

  • Simpler interface — literally just a list and two buttons
  • Smaller footprint
  • If all you need is “change MAC, done” — this is faster to figure out

Why TMAC is still better:

  • No presets
  • No CLI support
  • No vendor database updates
  • Less adapter info shown
  • No IPv6 config options

💻 4. Windows MAC Address Spoofer (Script — No Install, Portable)

For the command-line crowd. This is a batch script that runs in CMD — no install, no GUI, no bloat. Just a .bat file you double-click.

What it does:

  • Detects all network adapters on your system
  • Lets you pick which one to spoof
  • Generates a random MAC and applies it
  • Can revert to original MAC
  • Can set a custom MAC
  • Runs entirely through Windows’ built-in registry and network commands

How to use it:

  1. Download from https://github.com/Scrut1ny/Windows-MAC-Address-Spoofer
  2. Right-click → Run as Administrator
  3. Pick your adapter from the list
  4. Choose: Spoof (random) / Revert / Custom
  5. Done

Why use a script instead of an app:

  • Nothing to install. Nothing left behind. No traces in Programs list.
  • Drop it on a USB stick — use it anywhere
  • Fully transparent — you can read every line of the code
  • Works offline. No dependencies.

Best for: People who don’t want software installed. USB toolkit users. Anyone who wants to see exactly what’s happening to their system.

🐍 5. Universal MAC Changer (Python — Cross-Platform Power Tool)

If you use more than just Windows, this is the move. A Python-based MAC changer that works on Windows, macOS, AND Linux with the same commands.

Features that set it apart:

  • ~6,200 known vendor database built in
  • Set MAC from a specific vendor (make your adapter look like it’s from Apple, Intel, Samsung — whatever)
  • Random MAC from any known vendor (looks realistic, not obviously spoofed)
  • Auto-rotate — change MAC at custom intervals (every X seconds)
  • Search vendors by name
  • Cross-platform: same tool, same syntax, everywhere

How to use it:

  1. Needs Python 3 installed
  2. Clone: git clone https://github.com/StellarSand/universal-macchanger.git
  3. cd universal-macchanger
  4. Random MAC: python3 umac.py -i "Wi-Fi" -r
  5. Specific MAC: python3 umac.py -i "Wi-Fi" -m XX:XX:XX:XX:XX:XX
  6. Vendor spoof: python3 umac.py -i "Wi-Fi" -rv (random vendor MAC)
  7. Auto-rotate every 60 seconds: python3 umac.py -i "Wi-Fi" -r -t 60

Why this matters: Most random MAC generators spit out addresses that are obviously fake — they don’t match any real vendor prefix. Network admins can spot those instantly. This tool generates MACs that look like they belong to real hardware. Big difference if you’re trying to blend in.

⚙️ 6. Device Manager (Manual Method — Already on Your PC)

No software. No scripts. Just Windows itself. This works on most Ethernet adapters and some Wi-Fi adapters — depends on your driver.

Steps:

  1. Press Win + X → Device Manager
  2. Expand Network adapters
  3. Right-click your adapter → Properties
  4. Go to Advanced tab
  5. Look for “Network Address” or “Locally Administered Address” in the property list
  6. Select “Value” and type your new 12-digit MAC (no dashes, no colons)
  7. Click OK → Restart your PC

To revert: Same steps → select “Not Present” instead of “Value”

Limitations:

  • Not all adapters show the “Network Address” property — if it’s not there, your driver doesn’t support it
  • Many Wi-Fi adapters don’t have this option (manufacturers disable it)
  • Requires reboot to take effect
  • No random generation — you have to come up with or find a valid MAC yourself
  • Tedious compared to one-click tools

Best for: Situations where you absolutely cannot install anything and don’t have a script handy.

⚠️ What MAC Changing WON'T Do — Don't Get It Twisted

Changing your MAC is one privacy layer. It’s not invisibility.

It will NOT:

  • :prohibited: Hide your IP address — you need a VPN for that
  • :prohibited: Encrypt your traffic — VPN or HTTPS handles that
  • :prohibited: Make you “anonymous” on the internet — it’s a local network thing
  • :prohibited: Protect you from browser fingerprinting — that’s a whole different problem
  • :prohibited: Survive a reboot (in most tools) — unless you use presets, scripts, or Windows’ built-in setting

It WILL:

  • :white_check_mark: Stop Wi-Fi tracking across locations
  • :white_check_mark: Break the link between your device and previous sessions on a network
  • :white_check_mark: Bypass MAC-based access controls and time limits
  • :white_check_mark: Remove one more piece of your hardware fingerprint
  • :white_check_mark: Take about 5 seconds with the right tool

Think of it like this: VPN hides your identity on the internet. MAC spoofing hides your identity on the local network. Different layers, different threats. Use both.

:high_voltage: Bottom Line

If you just want it done: Technitium TMAC. Download, click random, click change. 30 seconds. Free forever.

If you’re on public Wi-Fi right now and can’t install anything: Windows Settings → Wi-Fi → Random hardware addresses → ON.

If you want no traces: The batch script from GitHub. Run from USB, change MAC, pull the stick out.

If you’re across multiple operating systems: Universal MAC Changer. Python, cross-platform, vendor-matched MACs.

Your MAC address is nobody’s business. Stop handing it out for free. :locked:
