Wasn't this the GUID (Globally Unique Identifier) of early 00s Windows? When did it change to GDID? Are they the same?

No relation. GUID is just a format for a 128-bit unique number, used throughout the software industry. This is a specific 64-bit number assigned to your Windows device.

Maybe try reading the writeup? GDID's are 64 bit for one thing, not 128 like GUIDs.
