Well, at the end of the line (i.e. when the final Win10 will be out) all these little useless things to you might be indeed very useful, particularly when it comes to the portability of 1 platform on many different devices.
I give them the benefit of the doubt, and all the time they need to fix what they have to fix. It's their job, not mine, to create a good OS.
I clearly understand your frustration, but so far my experience with Win10 has been a triumph. I use it everyday at work & at home. Rock solid. The only thing that bothers me is that for some reason the System Hardware Update 2015-01-27 keeps re-installing itself every other day. Otherwise, it is as good, if not better, than Win8.1.
