It's quite hard, but still not impossible, to keep a Windows installation from phoning home at every opportunity.

But there's a breaking point here somewhere when MS manages to shove so much crap into Windows and Office, that any sane sysadmin will have to answer "I don't know" when asked whether and where data processed on the device might get sent without the user's knowledge. At that point likely not even Microsoft will be able to make assurances with a straight face about the monster they created. Already these kinds of "oopsies" are par for the course.

We're at a point where pressing the Win key followed by CTRL+V will send your clipboard to MS servers on default Windows installations. Any user is one fat-finger missing the control key away from this. Pretty easy way to break the law if you're doctor.

I know it will get worse from here and my disdain for the people involved in this shitshow is immeasurable.

Of course many goverments and companies will not able to tolerate this new state of affairs. Once Microsoft fully loses their "trusted" status with these sort of clients, it will take them decades to regain it.
