Whether it was servers or workstations, Windows was the choice. This was because the software used could only be ran on Windows. I suspect there are many companies/government agencies/schools, etc that are in that same situation. Sure, there may be a *nix server here, an Apple product there, etc, but Microsoft definitely has the stranglehold.
Since Microsoft is in this position, and the software used by my workplace runs only on Windows, there will eventually come a time, when vendors have put out versions of their software that will run on WX, that all workstations in our workplace will be WX. I don't see this NOT happening.
This means, that unless someone took the time to configure a firewall to block all of the telemetry, etc, connections going out to Microsoft's "user data and profiling aggregation infrastructure", anything someone did on one of those WX machines, while at work, would essentially be tracked and logged by Microsoft and whoever they were sharing that data with.
I don't think people really understand what this means.
Oh, and do me a favor. Please don't suggest I use Linux. If a workplace like mine, or the others I've been at, could have used Linux instead of Windows, that transition would have happened years ago.
And another thing, there is a false sense of privacy among many about BYOD. As if using your iPhone or Samsung is going to leave you a trail free of crumbs. Free from every comment you make online, free of every post or update.
