Okay, can anyone explain to me why this is the third time in a row that I have to re-disable "fast startup" after a windows-update?

I know, some of you might think that windows sucks, and I agree, to some extent, but I still want to be able to play my games there.

So, is there any rational explanation for the fact that windows seems to suffer from some kind of amnesia when it comes to settings? I don't believe it was either bad intent or complete incompetence from the developers...
Is it a certain design decision? Or is is that hard to implement "persistent" settings storage?
