How to generate a less random GUID

[aaronfude]

Hi,

I would like all of my GUID's to start with letters AF (my initials,
which is a bit lucky) so I can then easily identify them as likely
mine. Is there a way to produce such ID's w/o doing it manually until
one get lucky?

Thanks,

Aaron

Not really.
You could automate the manual process by writing a program that
generates new GUIDs (using the Win32 API) until it gets one with AF in
front. But that program could run for a very long time...

Sure - generate a GUID and replace the first 2 chars with AF.

But then it would not be guaranteed to be unique anymore.

A GUID is not so much guaranteed to be unique as it is statistically very
unlikely to be a duplicate. Changing 2 chars in one lowers the odds slightly
but not much.

And how badly will the system malfunction if it happens to be a
duplicate of something else? What will happen?
