Who I have the same questioned this solution

Don't be in too much of a hurry if you have a Microsoft device (as opposed to Nokia or other manufacturer). I bought a Microsoft Lumia 935 and used it for a month or so before I signed up as an "Insider". I have had nothing but trouble since I upgraded to Windows 10. Right now I'm trying to figure out how I can do a hard reset when it crashes out of EVERYTHING, settings included.
