I see these 2 acronyms thrown around, and I was wondering if there are any differences between a GUID and a UUID?

+28  A: 

GUID is Microsoft's implementation of the UUID standard.

Per Wikipedia:

The term GUID usually refers to Microsoft's implementation of the Universally Unique Identifier (UUID) standard.

Not really. GUID is more Microsoft-centric whereas UUID is used more widely (e.g., as in the urn:uuid: URN scheme, and in CORBA).

Well a GUID (Globally Unique ID) is only unique for items on this planet, whereas a UUID (Universally Unique ID) should cover you anywhere terrestrial or extra-terrestrial

Assuming, of course, that there aren't alternate universes. :-)

It's the other way around. Cf Men In Black.

GUID is easy to pronounce: /gwid/; UUID isn't: /yew-yew-eye-dee/.
