Changing DHCP Vedor code in Windows?

Changing DHCP Vedor code in Windows?

Anyone know how to change the default DHCP vendor code in Windows from "MSFT 5.0" to something else? So far, I can't find it in the registry. I'm trying to create a tool for Windows against OS fingerprinting (OSfuscate):

I've got some success on TCP level stuff, but if the scanner is on the same LAN and it sees a DHCP request the vendor code gives it away. I know it's sort of a parlor trick security wise, but I think it's sort of cool. I'm testing against NetworkMiner that uses the Fingerbanck/Satori fingerprints.

Oh well, I found out how, but I had to patch the dll.

Here is the tool set:
