Old Windows, at 13 years, ancient really.
Hackers have improved their attack tools, now it’s time to update our defenses. Microsofts response is to leave the old castle walls behind and build something that is up to the task.
It won’t stop Target-like breaches, as the Target doors were left open, but to those of us who keep up with things it will be much safer.
I can see the point that this is not customarily how Microsoft operates.
But if I were Bill Gates, and had a heart, I’d try to help customers of the old stuff, by designing the new stuff to be easier to use in place of the old if nothing more.
