When Microsoft started using UUIDs[edit]

To help fill in the history for when Microsoft started using UUIDs (the "when" question is flagged in the article), I have a bit of information that might help someone search for the answer.

I attended a Microsoft conference at the Redmond campus in 1995 where a presenter gave information about UUIDs, how they are essentially unique, and that Microsoft was going to be using them.

That's not enough to put into the article, obviously, but maybe it'll help give a timeline if someone is researching this. — Preceding unsigned comment added by Chris uvic (talkcontribs) 18:20, 30 June 2021 (UTC)Reply[reply]

Other vairants of UUID[edit]

Reviewing logs in a web gateway, UUID Variant "e" was observed in the wild. This is not Random as fields 3 4 5 are the same between two seperate UUIDs

New Versions[edit]

There is a draft RFC which introduces versions 6, 7 and 8, as well as a form called MAX UUID.

I don't know if this proposal merits inclusion, or if we should wait until it is finalized.
