A secret agent running in the background, with my data stolen from the foreground? How queer! I see the battlegrounds shift from large networks to the personal computer, where malware, hand in hand with AI will steal the virtual crown jewels day after day, slurping and leaking PII data non stop.

AI will be baked in so deep into the Windows eco- and subsystem, that it's a wet dream come true for hackers and nation state adversaries. It's a huge win for everyone selling hacking and security, virtual cops and robbers, black hats and white hats: only the end users and already piss poor facilities will suffer, but they're just collateral damage in a war of numbers and terabytes of leaks.

Is it any more "secret" then other background services like search index?

Probably. Apart from the pun about a certain good looking employee of MI6 and his gadgetry, at this point I'm relatively sure not even Redmond knows how many different products they have called Copilot Something, let alone how to kill them with a single switch, but of course we will see.
