A MAC address is only supposed to be reasonably unique within a LAN. Since the MAC address is comprised of 6 bytes, 3 of which are a manufacturer's ID, this leaves us with 3 bytes of of unique data within a single brand of Ethernet devices. 3 bytes is just under 16 million. A UUID is a universally unique ID. http://www.dsps.net/uuid.html One of the uses was in web components that needed to be called the same way, but expire when a new version was available. You could call it with it's UUID and be sure to get the one you wanted. If you look through a windows registry, you should see quite a few of them for many components on your machine. Yes a UUID could be tracked back to the owner. It could be forged by editing the binary. It could be changed completely or even omitted. If you used open source software you could even view how it was created, and if so inclined, remove the sections of code that inserted it. Give the image editing software called "The Gimp" a try, you may find it does enough of what Photoshop does to not need Photoshop.http://www.gimp.org/
