I just spent 10 plus hours this weekend dealing with this huge issue with surface pro 4.
The Windows start screen disappear and things stopped working. Tried to reformat that was a disaster. Took all weekend to figure it out myself. And I am a techie. A normal person wouldn't put up having a reformat fail in the middle. Going to have to buy a jump drive and redownloading and transferring files to jump drive and restoring.
Apple has a much easier process if there is a problem. All you need is an Internet connection to resorts from Mac App Store.

Or you could have just dropped it off at the Microsoft store and let them sort it out, similar to how Apple handles it. Of course that's assuming a MS store is near you. I'm still not disagreeing, Windows can certainly be more complex. I've been lucky and not had to deal with any of those issues over the course of owning probably 20 plus different windows tablets including 4 SP3's and 2 SP4's. I'm not saying I haven't had any issues, just not extreme ones like yours.
But yeah, if you are close to a Microsoft store just walk it in and have it replaced. Alternatively you can ship it in and have it replaced as well. You probably don't even have to do it through warranty as you are still in the return period.
