In an education setting, it does make a lot of sense to lock down the student laptops to ensure that they
a) Can be managed easily over the cloud
b) Can't be easily tampered with or ruined by students
c) Don't get a plethora of games and other distractions installed on them
I can see it helping said causes above, but is by no means a foolproof solution.
I see it as more of a trojan for Windows to eventually do away with applications that aren't on it's store. MS has been pushing their store damn hard, and the telemetry that is tied to their default web, video, music, and photo apps really grinds my gears when I try and change them and am "helpfully reminded" that Microsoft has it's own info sucking defaults. Then it annoys me by asking if I would like to change my mind.
No. I know what the f**k I am doing Microsoft.... but more to the point, I know what you are trying to do.
I know what the S stands for in Windows 10 S.
