Sounds like 'Hot Bag mode'...with Microsoft bringing back historical features.
"With a hopeful tone, Microsoft suggested devices might automatically update overnight, when students weren't present."
This sounds like it's bringing back those early days of the Surface tablet 'hot bag mode', where updates were attempted and you find the tablet mode device, packed in a bag, runnning at 90+ degrees celsuis, with the fan blaring. And once it cools, the Graphics begin to 'blue screen', due to an overheated surface mounted GPU.
