@MS hybrid boot
I have had ideas to speed up AOS4 bootup with a little bit similar feature. (before I heard about M$ version)
The environment does not change between bootups usually, therefore hybrid can be good.
I've also noticed that hybrid is now the windows standard way. Without hybrid shutdown all kinds of weird things can happen. To me it seems they test mainly hybrid shutdown and fast startup at M$ & third parties (so, the real real cold boot seems less robust).
