The critical bit is:

Intel releases critical Core 2 Duo microcode update - Silently

Around April 10th, 2007, Intel released a microcode update (BIOS flash
to the rest of us) so resolve several major issues with how Intel Core 2
series processors operate.

So... If you've done a recent BIOS upgrade and your motherboard
manufacturer was up to date, you may already be covered...

>From that date from so long ago, it must be well tested by now! Still
needs checking if you're covered.

At least the Windows 'update' makes it all easier for the Windows people.

Am I really so badly behind the times? Anyone hear of this?
