How to Spoof Your MAC Address in Windows 7

Just recently I was doing some security consulting for a corporation in the area, and had to use a Windows 7 Professional computer, unlike my normal Linux setup. I tried everything to spoof the MAC address and it wouldn’t work. After doing some intense research and looking at Microsoft’s TechNet forums, Intel postings, and just random websites, I found a few different options, ranging from costing a few dollars, to a few free solutions, so I said what the heck and gave it a shot, starting first with what I knew normally worked, regedit. Needless to say, it didn’t work, and discouraged me. Then, attempting to go to Network and Sharing Center, and modifying the properties of the adapter, the option that was “supposed” to be there wasn’t, and nonetheless I was fed up, and well, said what the heck, and tried SMAC MAC Address Changer, which set me back $19.99 (I know there was a trial, but the trial was more of a demo instead of a trial).  Then, out of the worst luck possible, SMAC didn’t work, at all. Fed up, I just put it away for the day, with my mind going back to the drawing board. Funny thing is, I felt like I had tried everything, but didn’t realize (at the time) I jumped the gun on a few options, and decided to take another look. After finding a program that a TechNet poster recommended, I tried MacMakeUp, because, well it was a free software after all, and I didn’t have anything to lose. And IT WORKED! So, I have replicated the steps below, for anyone who is sharing all the problems I had.

Step 1: Download MacMakeUp from Softpedia (

NOTE: Please be aware that I, Michael R. McNeill, as well as, Connected Site Solutions, Softpedia, or anybody else will NOT accept responsibility for the software you are downloading. Softpedia does check the files for malware, but nobody can guarantee 100% that they are clean. Keep in mind that the integrity and safety of any downloaded software may be affected if it is modified via unofficial patches or other methods. For your own protection ALWAYS check downloaded files for viruses.

Step 2: Open Control Panel

Step 3: Select Network and Internet

Step 4: Select Network and Sharing Center

Step 5: Select “Change adapter settings” in the left sidebar

Step 6: Select which adapter you wish to modify and right click on disable.  (KEEP THIS WINDOW UP/MINIMISED! DO NOT CLOSE IT!)

Step 7: Continue through the User Account Control (UAC) Prompt (if applicable)

Step 8: Extract the downloaded ZIP file.

Step 9: Right click on MacMakeUp and select “Run as Administrator”

Step 10: Continue through the User Account Control (UAC) Prompt (if applicable)

Step 11: Select which adapter you want to change

Step 12: Enter your Modified MAC Address, or hit “Generate Random” and select “Completely Random MAC”

Step 13: Select “Change”

Step 14: You should get the message “MAC spoofed. Remember to disable/enable the adapter!”

Step 15: Open the minimized Network Connections window and right-click the adapter you just spoofed. Select enable.

Step 16: Continue through the User Account Control (UAC) Prompt (if applicable)

Step 17: To verify, search in the start menu for “cmd” (without the quotes) and when it finds CMD right-click it and select “Run as Administrator”.

Step 18: Continue through the User Account Control (UAC) Prompt (if applicable)

Step 19: Now in the command prompt type “ipconfig /all” (without the quotes) and look for the adapter you modified!

Step 20: You should have a modified MAC! Congratulations!
