This is an interesting utility - and I'd not heard of it until yesterday! Field Medic is an official Microsoft utility, for Windows Phone 8.1 and Windows 10 Mobile, designed for when Microsoft support helps you remotely. The idea is that every last minute detail about your hardware and software is gathered, along with real time reporting on what the OS is doing. And it's free, of course. Of zero interest to casual users unless they have a problem, but very interesting for uber-geeks and AAWP readers!
