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

I don't know what's new on this. For the last two years all Office apps I own have insisted on saving to OneDrive first. I have always had to explicitly click on the path and select another folder. Every. Single. Time.

And on Mac things like TextEdit and Apple’s own office tools save them on iCloud by default.

You can turn that off in Settings.

For now.
