@ovinguyen, first of all thanks for sharing. According to the features description the tool can find both MAK / Retail key, but the video don't show Retail. Maybe, because the video is demonstrating some older version the tool.
Second, I just did a VirusToal and it failed badly. The current detection ratio is
12/54 .
