testing win7 mac address changer

Windows 7
using win7 mac address changer v2.0 (zokali.com)

how can I tell that this device is working

I try cmd.exe ipconfig and search for new mac address and can not find

try "getmac /v" or "ipconfig /all"

smac 2.0, or probably a much higher version number by now, has always worked pretty well. I'm not sure if it's still as popular now, but I remember years back that quite a few people would talk about it here and there. I tried it once and it worked for me, but it was so long ago that I couldn't even tell you what I did totally.
