This can be contrasted to a programmed address, where the host device issues commands to the NIC to use an arbitrary address.
The above is what you quoted yourself, alisoncc.
By change, we don't mean altering the hardware MAC address, we mean using the NIC driver software to assign a replacement MAC address.
You can change the MAC address in every version of Windows, at least since Windows 95 and NT server 3.5, and that's on anything from the cheapest PC to rack-mounted servers.
In fact, many SOHO broadband routers allow you to do this (my Linksys does), as it frequently used to be necessary for the router to spoof the MAC address of the PC that first registered the broadband connection with the ISP. Fortunately, those days are largely behind us.
I'm afraid, old chap, that mixture has summed it up in one word - rubbish.
