uuidv1 sequential, by default

On *current* Microsoft Windows OS, when creating a .LNK file, Microsoft Windows embeds :
- the source hostname
- an UUIDv1, itself containing :
- the last MAC address you have
- a timestamp

End of the Melissa story, I found 6 UUIDs in the sample. They have been added to my database. Only two have the same "node" (MAC Address) field, b066d7192d0a.https://t.co/L3sKunQkmfhttps://t.co/i2bN2IY1nN

Fun fact : there is a timestamp and a MAC address in the UUID version 1.
This can be used to know that this specific Dell machine has been used all over 1998 to define those 6 UUID.
