Last time we saw the new ribbon interface being demoed and now yet another reveal, full of awesomeness this time. Long time requested feature on Windows is a faster boot time, which was never implemented till now.
Usually what happens when you shutdown your windows machines : Kills all processes, kernel shuts down, and during startup : Loads kernel and starts all apps

MS explains this in an image :
Microsoft claims this process makes Windows 8 50-70% faster than the current boot times. Hard to accept ? Well, they got a video demo for that, warning : dont blink
