About GUID
GUID (Globally Unique Identifier) is Microsoft's name for a UUID — the same 128-bit standard. The only real difference is presentation: GUIDs are conventionally written in uppercase and wrapped in braces, e.g. {D290F1EE-6C54-4B01-90E6-D701748F0851}. This generator produces a version 4 value in that format.
