Word documents will be saved to the cloud automatically on Windows going forward

We recently started rolling out 11 at work, and we have all sorts of group policy hacks to disable stuff... one thing I noticed is that despite copilot being disabled, the button still appears at the top of every office app. I'll have to check on the weekend, but I wouldn't be surprised if we hard enable this option as we have our own OneDrive instance to replace our terabytes of network shares.

FWIW, I don’t have any copilot buttons anywhere (checked Excel, Teams, Outlook), on 24H2.
