This has been a typically thoughtless series of actions from Microsoft. Anyone can download and install apps from the store, but commenting requires a personal account? There are no download restrictions for many apps, we've not configured restrictions or control at our workplace, but folks who can download stuff can't comment on that stuff or review it because they're a workplace MS user? What's the point of that?
Many folks are workplace only MS users and won't touch MS with a 10 ft pole in their personal life (and who can blame them when Microsoft continually conducts itself like this). This is NOT the right way to encourage MS into people's personal lives. Blackmailing people to create personal accounts (requiring MS to know more of their email addresses) by restricting their abilities is narcissistic. It's yet another low marketing blow from you Microsoft. Stop trying to think of ways to frame your sociopathy as a service to others. You're fooling no-one.
From "finish setting up your computer" (translation: "let us ask you marketing questions and throw a bunch of in-app transaction bloatware offers at you without disclosing that fact".), to making the notification centre popups appear on top of the clock and icons which said popups quite often refer to, thus preventing access to them if MS still has something to say, and in the same breath forcing users to not be able to move the taskbar to other parts of the screen to work around this issue... why? Because "we have secret plans which require the old taskbar has to go... oh but our secret plan is still a long way away, so you'll just have to live with this regression in common sense for now", and "How good are we?!!" popups appearing on things which we've not yet even had a chance to see and use (because the popup is on top of it!)... Your teen insecurity issues are not just showing at the moment Microsoft, you are parading them through the central business districts of every major city in the world.
